3. GEOPOLYMER CONSTRUCTION MATERIALS

[0127] FIGS. 1A-1C illustrates a traditional framed wall system 100 and exemplary wall systems 120 and 130 constructed using the building materials of the presently disclosed subject matter. FIG. 1A shows a traditional wall system 100 comprising approximately 10 layers of different building materials from interior to exteriorsheetrock 101, framing 102, insulation 103, sheathing 104, flashing 105, building paper 106, wire/lath 107, scratch coat 108, brown coat 109 and top-coat 110. FIG. 1B shows a first exemplary 4-layer wall system 120 for use in new construction. The wall system 120 comprises sheetrock 101, insulation 103, studs 112, and a four-inch exterior wall 114, manufactured using the geopolymer formulation disclosed herein. FIG. 1C shows a second exemplary wall system 130 for use in new or existing construction. The wall system 130 comprises sheetrock 101, framing 102, insulation 103, sheathing 104, flashing 105, building paper 106, wire/lath 107, and a one-inch exterior wall covering 116, manufactured using the geopolymer formulation disclosed herein.

[0128] Traditional framed wall systems require approximately 10 layers of different building materials i.e., 10 revolutions around the structure (FIG. 1A). From the exterior topcoat of stucco to the finished sheetrock interior, each of these layers require a different skill set and manpower. In one embodiment, the wall system of the subject matter disclosed herein eliminates all but 4 layers, including any combustible materials (FIG. 1). In one embodiment, the wall system of the subject matter disclosed herein eliminates all but 8 layers (FIG. 1C). This allows for a dramatic reduction of construction time, labor costs and potential application errors. Most importantly, it allows for a safer, faster, stronger, and longer lasting finished product that emulates the properties and appearance of traditional structures. Further, because of its unique properties, the subject matter disclosed herein allows for new architectural designs, applications, speed, and cost of production that have not been previously achievable.

[0129] To address the loss of property and life due to natural disasters, different types of building materials are disclosed in the embodiments as discussed above.

The superior structural strength and non-combustible properties of such products when compared with Portland cement-based tiles make the disclosed geopolymer formulations an attractive option both from an economic and aesthetic perspective. Among these roofing products, sheet of tiles offers particular benefits including but not limited to reduced weight, which reduces the load on the trusses. This results in improved construction design, speed of installation, and/or less material costs. FIGS. 2D and 2E illustrate exemplary siding and tiles respectively.

5. EXAMPLES

Example 1. Exemplary Building Materials

1.1. Accessory Dwelling Unit (ADU)

[0197] This example describes an exemplary method for manufacturing an ADU using Formulation A.

[0198] Method: A base pallet was first assembled. Exterior wall forms were set up using silicone covered OSB (). A 3/16 basalt rebar was installed vertically, 12 on center and horizontally, 18 on center. Next, interior wall forms were set up using prefinished maple plywood (). Formulation A (6200 lbs.) was pumped into the forms in less than 1.5 hours. The material began to set in about 4-6 minutes. The interior forms were removed after 18 hours followed by removal of the exterior forms after 30 hours.

[0199] Results: The material began to harden within 4 minutes of hydration during the pour. The internal temperature of formulation did not exceed 146 F. throughout the entire process, which avoids the possibility of spalling when poured in large quantities. The formulation when poured in large/thicker quantities, hardened quickly, and cured to a compressive strength of 2500 psi within 12 hrs. The compressive strength was increased to 3200 psi in 24 hours (55% cured) and to 5500 psi or higher after 14-21 days. A complete roof system was then installed, along with doors and windows (FIGS. 2A-2C). The building envelope was weather tight within 48 hours of pour, allowing for all interior work to proceed without weather interruptions.

1.2. Siding and Tiles

[0200] This example describes an exemplary method for manufacturing siding and tiles using Formulation A and Formulation C.

[0201] Method: One-quarter inch () walls were affixed to 8-inch24-inch and 12-inch24-inch wood grained siding or tiles to create molds. Additionally, three-quarter inch () walls were affixed to a 24-inch24-inch wood grained panel to create a third mold. 100% silicone was applied to the siding or tile surface on all 3 samples using a brush to allow easy release of the Building Armour from the form. Black pigment was added to the dry mix for the 24-inch24-inch sample. Mixing for all three molds were performed using a Hobart mixer with paddle blade attachment, at speed 1. After pouring, samples were placed in a 160 F. oven for 24 hours. Siding and tile samples were released from the forms and visually inspected.

[0202] Results: FIGS. 2D and 2E show exemplary siding and tiles manufactured using the method described above. The samples showed relief detail down to 1/32. The black tinted sample was evenly coated throughout each surface. All samples were indistinguishable in relief detail from the original pieces used to make the molds. Exterior siding and tile panels manufactured using the geopolymer formulations disclosed herein are indistinguishable from wood or vinyl siding and tiles. These sidings and tiles have several advantages, including but not limited to non-combustibility, durability, impact resistance, mold resistance, fungus resistance, pest resistance, and resistance to wrap and/or peel, which reduces maintenance costs. Additionally, the products use non-recyclable waste products, and the method of manufacture as disclosed herein do not contribute to the carbon footprint, which are eco-friendly features that benefit the industry.

3.1.3. Compressive Test 3

[0225] A total of eleven (11) 2-inch4-inch grout cylinder samples were cast using Formulation A (comprising Fly Ash, 60% w/w; GGBFS, 40% w/w) for testing. For samples 1, 2 and 3, 6000/lbs of Formulation A was placed in a large bag and suspended over a rotor-stator pump/mixer. The mixer drew the formulation from a hopper, hydrated the formulation and mixed (50 sec POC Pour samples, or 3 min for POC with Color samples) using a downline auger. The hydrated formulation was pressurized into a 35 mm diameter hose and poured into the forms (similar to pouring an above ground foundation). For control sample 4, the formulation was mixed for 3 minutes with water, at 324 rpms in a planetary style food grade mixer, poured into the forms. All samples were oven cured for 24 hours at approximately 160 F. Grout cylinder samples were labeled in accordance with their material properties as follows: Control (2 samples), proof of concept (POC) w/Color (3 samples), Skim Coat (2 samples) and POC Pour (4 samples). Cylinders were prepared and tested in general accordance with ASTM C39.

[0226] Results: The results of the compressive strength testing are shown in Table 6. The results indicate. The industry standard requirements for stucco is a compressive strength of between 1800 psi and 2000 psi. The results show a compressive strength that exceeds those requirements by 150%-200%. Sample 5, which used Formulation B as a skim coat also exceeded the industry standard requirements by more than 100%. Sample 6, which used Formulation C as a poured-in-place application also exceeded the industry standard requirements by 150%-250%.

3.1.4. Recycled Concrete Aggrgate (RCA) Test

[0227] This test was designed to determine the compressive strength of a 700%:30% mix ratio of Formulation A with Recycled Concrete Aggregate (RCA).

[0228] Method: Formulation A was prepared using sand (Home Depot, source: MSU) and 18 mm basalt fibers. 150% (w/w) water was added to the dry mix and the ingredients mixed using a Hobart mixer with the paddle blade attachment, at speed 1. Mixing initiated the gelling phase after 13 minutes. Two (2) 2-inch4-inch sample cylinders were filled with the mixture and allowed to set (30 minutes). The cylinders were placed in a 200 F. oven for 40 minutes.

[0229] Results: The two cylinders were tested for compressive strength (Testing Engineers Inc. San Leandro, CA) and found to have compressive strengths of 5,470 psi and 5,530 psi for the formulations that included RCA (see Table 7, sample #23, 24). These compressive strengths are significantly above the 2500 psi-3000 psi requirements for poured-in-place wall constructions. RCA being a waste product with limited re-use applications, its inclusion in the geopolymer formulations disclosed herein introduces eco-friendly practices to manufacturing. The low nominal costs associated with RCA also provides economic advantages by reducing overall manufacturing costs.

3.2. Bond Strength Tests

3.2.1. Bond Strength for Cold Joint Test 1

[0230] A total of four (4) grout tiles and two (2) 2 by 4-inch grout cylinder samples were cast and provided by you for testing. Grout tiles for bond testing were reportedly coated with the geo-polymer after specific cure times. Tiles were identified by their cure times and were labeled 4 hours, 24 hours and 30 days. A tile with no coating was labeled as a control. Three (3) pull tests were performed on each tile. Per ASTM C-1583, Aluminum test fixtures, 50 mm diameter, were adhered to the drilled sample using a two-part epoxy adhesive. This assembly was left to cure a minimum for 24 hours. Bond testing was performed using an Elcometer Model F510-50T (serial #TJO7128 & calibrated on Nov. 16, 2022) at a rate of 29 psi/sec. Grout cylinder samples were labeled in accordance with their material properties as follows: (2) Green/Substrate, (3) Red/Overlay. Cylinders were prepared and tested in general accordance with ASTM C39. The results of these tests shown in Tables 6 and 10 show that materials manufactured using the formulation disclosed herein passed the bond strength test because the sample did not break at the joint when compared to the control sample.

3.2.2. Bond Strength for Cold Joint Test 2

[0231] A total of four (4) grout tile samples were cast for testing. Grout tiles for bond testing were coated with the geo-polymer after specific cure times. Tiles were identified by their cure times and were labeled 4 hours, 24 hours and 30 days. A tile with no coating was used as control. Three (3) tests were performed on each tile. Aluminum test fixtures, 50 mm diameter, were adhered to the drilled sample using a two-part epoxy adhesive. This assembly was left to cure a minimum for 24 hours. Bond testing was performed using an Elcometer Model F510-50T at a rate of 29 psi/sec.

[0232] Results: The results of the compressive strength testing is shown in Table 11. Considering that the typical range for adhesion values for Portland cement-based stucco is 3-5 psi, the results presented here indicated that adhesion values for the geopolymer formulations disclosed herein are significantly superior and can be raised to at least 200 psi with no cold joint.

3.3. Flexural Strength Test

[0233] This test was performed in accordance with the ASTM C-78. Briefly, one sample (Test #1) was mixed for 3 minutes in a lab mixer (108/rpms), allowing for a total of 324/rpms. A second sample (Test #2) was mixed for 3 minutes with a drill for a total of 1500/rpms. A third sample (Test #3) was mixed for 3 minutes, with a drill as for Test #2, but for a total of 4500/rpms. The results of the text are shown in Table 12 below.

3.4. Adhesion Properties

3.4.1. Adhesion Test 1

[0234] This test was performed to determine adhesion of the formulations disclosed herein to industry approved standard substrates.

[0235] Test walls (128 sf each) comprising (i) paper and lath over an oriented strand board (OSB), (ii) chicken wire over OSB, and (iii) OSB alone (FIGS. 3A-3D) are sprayed to a thickness of 1 with Formulation A. The spray was allowed to cure for 7 days.

[0236] Results: The formulation was found to adhere to all substrates. From an operational perspective, five workers could handle the work, spraying at 125 lbs/min and completing all 3 walls in about 20 min. Thus, a 1500/sf house can be sprayed 1 thick in less than a day as opposed to weeks when using traditional stucco.

3.4.2. Adhesion Test 2

[0237] This test is performed to determine adhesion of the formulations disclosed herein to basalt mesh. 3 of Formulation A was poured into a form in two pours. The first pour consisted of 2 into mold. A 50 mm basalt mesh was then laid on top of the 2 of cured Formulation A. An additional 1 of Formulation A was then poured on top of the 50 mm basalt mesh. FIG. 4 illustrates a test surface 400 comprising two layers of building materials 402, 403, and 404 constructed using Formulation A interspersed with basalt fiber mesh layers 401 for improving adherence.

[0238] Results: The cured formulation was found to adhere to uncoated basalt fiber mesh. It was confirmed that the fiber mesh helped keep the building material intact during a fracture.

3.5. Joint Properties

[0239] Cold joints tend to have higher permeability compared to monolithic joints. In cold joints, the interface between two sections may not have proper bonding, resulting in pathways for moisture and other substances to penetrate into the structure. This leads to corrosion and deterioration of the structure over time. A monolithic joint is a substantially unified, seamless connection or structure formed as a single entity without separations. As applied to construction materials, a monolithic joint embodies a strong, durable connection where materials are chemically and/or physically fused into a single, cohesive unit. To determine whether building materials made using the formulations disclosed herein have cold or monolithic joint properties, hemispheres made using various formulations were tested using joint compounds made from various formulations, in different combinations as shown in Table 13A.

TABLE-US-00011 TABLE 13A Exemplary formulations used for joint properties Formulation for Exemplary Formulation for Building Material (Spheres) Joint Compound Formulation A Formulation A Formulation B Formulation B Formulation C Formulation C Formulation A Formulation B Formulation A Formulation C Formulation B Formulation A Formulation B Formulation C Formulation C Formulation A Formulation C Formulation B

[0240] Spheres made from the indicated formulations were cure an cut in half. The hemispheres were then glued together using the indicated joint formulations. FIGS. 5A-5B show a representative experiment using Formulation A for the building material and Formulation A for the joint compound. The hemispheres 501 and 502 were glued using Formulation A 503, followed by curing the joint prior to testing.

[0241] Results: The joint formed between the two hemispheres was found to have monolithic joint properties. This is advantageous since the conjoined structures behave as a single structure that is impervious to the elements thereby eliminating the costs and resources associated with maintenance and repair. These results were confirmed through bond testing performed by a third party per ASTM C-1583 (See Tables 10 and 13B).

TABLE-US-00012 TABLE 13B Compression Test for products using Formulation A E84 Batch + E84 Batch + E84 Batch + 12 mm fibers 12 mm fibers 12 mm fibers and pigment + Properties and pigment and pigment additional H2O Diameter (Inch) 2.0 2.0 2.0 Length (Inch) 4.0 4.0 4.0 Area (Inch.sup.2) 3.14 3.14 3.14 Age Tested (hours) 41 41 41 Ultimate Load (mean lbs.) 15700 14660 11610 Ultimate Strength (mean 5000 4670 3700 psi)

[0242] Similar results were obtained for all combinations of the formulations. The indicated formulas were also tested on existing, cured, hardened, and broken Portland cement-based concrete. These tests showed that the formulas effectively repaired cracks, making them watertight. Furthermore, the formulas create a chemical bond between new and old concrete materials when bonding cold joints, resulting in a seamless, monolithic structure. This unique property eliminates the weak interface found in traditional concrete repairs, ensuring long-term durability and greater flexibility in construction and repair schedules. Such features observed for the geopolymer formulations disclosed herein are superior to those achievable for other types of building materials including Portland cement-based products.

3.6. Water Intrusion Test

[0243] This test was performed to determine the ability of building materials 600 manufactured using the formulations disclosed herein to exclude water from seeping into the interior of the structure.

[0244] Method: A base (7.5-inch7.5-inch) 601 and side panels (6-inch6-inch-inch slabs) 602 were manufactured using Formulation A. The slabs were affixed to the base using Formulation A as mortar 603 at the joints to make a box that was open at the top for observation (FIG. 6). The box was submerged in water, 604 and visually inspected for entry of water at various times from 30 minutes to 96 hours.

[0245] Results: No moisture was detected on the interior of the box for the entirety of the test period indicating that the slabs, base and mortar joints were impervious to moisture.

3.7. Appearance and Definition Test

[0246] This test was performed to determine whether materials created using the formulations disclosed herein are able to capture subtle architectural definitions on the mold.

[0247] An acrylonitrile butadiene styrene (ABS) or PVC pipe was cut longitudinally and screwed to a wooden form. Formulation A was poured into the form, and after ensuring the absence of air bubbles by tapping, allowed to cure overnight at ambient temperature.

[0248] Results: It was observed that the cured material was able to pick up as little as a 1/32 scratch in the mold. These features are particularly beneficial when manufacturing exterior finishes with high definition (described in the next section). Also, the cured material is not permanently bonded to ABS/PVC plastics, which increases the ease of removing structural products prepared by the methods disclosed herein. The building material manufactured using the exemplary Formulation A (with no dye added), had a green color with sheen (FIG. 7). The material had efflorescence, which was neutralized with a mixture of baking soda and vinegar in water. After 14 days, the material can be polished to a desired luster.

3.8. Color Bonding and Manufacture of Exterior Finishes

[0249] The ability to manufacture exterior finishes such as siding and roofing using the building materials described herein was also evaluated. To do this, OSB wood embossed siding was cut to 12 lengths, stacked in a form and coated with silicone. A desired dye (color) was doped into the dry Formulation A composition. After addition of water and mixing, the Formulation A containing the dye was poured into the forms.

[0250] Results: This study confirmed the ability of creating high definition, exterior finishes including, but not limited to siding panels, stone molds, soffit panels, and roof tiles. This allows one to be fire-proof and protect any structure.

4.1. Burn Tests

4.1.1. Burn Test 1. Burn Time of Old Stucco (Stucco from Preexisting Structures

[0251] Test: To understand the thermal properties of building materials comprising the formulation disclosed herein, a 40-year-old stucco sample was removed from an existing structure.

[0252] A burn test was then performed on both the existing 40-year-old conventional stucco (control sample), and the same control sample with of Formulation A applied by hand trowel. The surface was neither washed nor cleaned prior to testing. One-fourth of Formulation A was applied to control within 10 min of hydration and allowed to cure for 60 minutes in an oven at 160 F. Both control and test samples were heated using a blow torch containing MAPP gas, to approximately 3500 F. and recorded the time needed for the heat to transfer to the back of the stucco, reaching 350 F.

[0253] Results: The results showed the time it took for the heat to transmit through the control sample which occurred in 298 seconds. Whereas the transfer of heat through the test sample with one-fourth of Formulation A was delayed to 410 seconds.

[0254] Conclusion: Upon continued testing, it is concluded that doubling the thickness does not double the delay time. It was also observed after testing that the 40 years of paint and of the original stucco was impregnated. Also, the testing temperatures of about 1900 F. were higher than the testing temperatures of 1382 F. used by testing agencies for their standardized tests per ASTM (which is the average temperature of a structure fire).

4.1.2. Burn Test 2. Burn Time of New Stucco

[0255] Test: A 44 stucco sample was poured to a thickness of 1 with Formulation A. After allowing the sample to cure outside for seven days, the sample was then burned for 45 min using a 199,000 BTU torch at 1900 F. Visual inspection of the sample revealed minor surface cracking and discoloration. The thick charred material was scraped and removed. The thick layer was replaced with a thick layer of Formulation B by method of hand application with a trowel. The sample was allowed to cure outside for seven days before performing the heat transmission test as described for Burn Test 1.

[0256] Results: The results showed no change in time transmission of heat from the front to the back of the sample.

[0257] Conclusion: These studies therefore revealed that extreme heat (1900 F.) despite some visual cracking and discoloration, extreme heat did not cause permanent damage to the building material of the presently disclosed subject matter. This indicates that the disclosed materials are amenable to aesthetic repairs without affecting their thermal protective properties.

4.1.3. Burn Test 3. Burn Time of New Stucco

[0258] Test: This test was performed to evaluate the thermal properties of 1 thick stucco on a larger scale, using Formulation A to determine how quickly heat transfers through the material to the wooden framing members that have a combustion point of 350 F. A 48 stucco sample of 1 thick, was embedded with thermocouples using Formulation A. After allowing the sample to cure for seven days, the sample was burned for 45 min using a 199,000 BTU torch at 1900 F. In a related analysis, the temperature was taken on the front surface, as well as the back surface adjacent to the burn site was also measured.

[0259] Results: The amount of time needed for heat transmission to reach 350 F on the back side of the sprayed stucco panel was found to be 45 min.

[0260] Conclusion: This time frame proves to be longer than most external fires have fuel to burn.

[0261] Additional Test: While the test point of the torch on the outer surface reached 1900 F., adjacent test points on the outer surface 18 away failed to register temperatures above 150 F. (i.e., low heat conductivity). Once the burn test was complete, 55 F. water was applied with a water hose, to the exact spot of the burn point, to see if introduction of cold water would show any signs of degradation or spalling.

[0262] Results: There were little to no signs of degradation and more importantly, there was absolutely no spalling.

[0263] Conclusion: These results show that we have a very low heat conductivity, which would suggest that first responders would be able to apply water directly to a burning structure without the risk of spalling thus limiting bodily injury or other damages caused from spalling material.

4.1.4. Burn Test 4. Burn Time of New Stucco

[0264] This test was performed to evaluate the thermal properties of 1 thick stucco on a larger scale, using Formulation A to determine how quickly heat transfers through the material to the wooden framing members that have a combustion point of 350 F. in a real-world application. For this test, the specimen was burned at a temperature of 1400 F. until failure, that is, the point at which the back side of the sample reached 350 F. (1382 F./750 C. is the temperature used for ASTM standard tests per the International Building Codes). The specimen for this test was burned for over 1.5 hours at 1400 F., at which point the test was terminated, as the registered temperature on the backside of the specimen never rose above 275 F.

[0265] Conclusion: These results suggest that the material, when applied at 1 thick, could prevent the transfer of heat from an external heat source of 1440 F., from reaching the framing members to a combustion point of 350 F., for at least 1.5 hours, allowing for the fire to exhaust its fuel source and allow the internal framing members of the structure to remain intact.

4.2. Combustibility Test Per ASTM E-136:

[0266] Standard Test Methods for the Behavior of Materials in a vertical tube furnace: A standard test was used to test the behavior of materials in a vertical tube furnace. Briefly, test samples (#1 to #4, each 1.51.52, FIG. 8A) were dried at about 140 F. for at least 24 hours (but not more than 48 hours) and then placed in a desiccator to cool for at least 1 hr before testing. A Vertical Hot-Air Ignition Furnace, consisting of an electrical heating unit and a sample holder, was set at a temperature of 138210 F. (7505.5 C.). The test sample was lowered into the furnace. Observations were made to the time of flaming of the specimen. The temperatures of the thermocouples are recorded. The test was continued until the temperature at the thermocouples had reached maximum, or until it was evident that the specimen did not pass this test.

[0267] If at least three of the four specimens tested meet the individual test specimen criteria, the test was recorded as a Pass. When the weight loss of the test specimen is 50% or less, the material was deemed to have passed the test if, the recorded temperatures of the surface and interior thermocouples did not, at any time during the test rise more than 30 C. (54 F.) above the stabilized furnace temperature and there is no flaming of the specimen after the first 30 seconds. If the weight loss of the specimen exceeded 50%, the material was considered to have passed the test if, the recorded temperatures of the surface and interior thermocouples do not at any time during the test rise above the stabilized furnace temperature and no flaming of the specimen is observed at any time during the test.

[0268] Results: The test results of the flame spread, smoke and temperature tests shown in FIGS. 8B-8F and Table 14. indicated that the test material was not combustible. The submitted samples were thus found to meet the classification as a non-combustible per testing to ASTM E136.

4.3. Ignition Resistant Test Per ASTM E-84

[0269] Test samples (22 W24 L1 Thick) were placed in a conditioning room (maintained at 705 F. and a relative humidity of 525%) for a minimum of 48 hours prior to testing. The test was conducted in accordance with 2021 IBC Section 2303.2 following ASTM E84 and ASTM E2768-11 (2018), extending an additional 20 minutes. Briefly, the test sample was loaded onto the water-cooled ledge of a fire test chamber, stacked end to end on the chamber ledge. The chamber lid was lowered into test position with a non-combustible concrete board placed between the specimen and chamber lid. A draft of 240 feet per minute was maintained inside the test chamber throughout the test period by the means of an electronic fan afterburner and an electronically controlled damper door system located downstream of the test chamber in the exhaust ducting. The test was started when the test flame was ignited at the front of the test chamber. An electronic photocell system located in the exhaust system downstream from the test chamber was used to plot the smoke developed for use in calculating the smoke developed index. while a technician plotted the flame spread distance used in determining the flame spread index. The test was run for a 10-minute duration to determine the Flame Spread and Smoke Developed Index and continued for an additional 20-minute (20 minutes extended) period with Maximum flame spread recorded. Testing was extended for an additional 20 minutes, and observations made regarding significant progressive combustion and flame spread through extended duration. Testing was performed in accordance with the following: [0270] a) Section 2303.2 of 2021 International Building Code, referencing ASTM E84-18b, 10 minutes or 20 minutes extended. [0271] b) ASTM E2768-11(2018) Standard Test Method for Extended Duration Surface burning characteristics of Building Materials (30 min Tunnel Test). [0272] c) Test method to UBC No. 8-1 and SFM 12-7A-5 per Chapter 7A of the 2019 California Building Code, ignition-Resistant Material 30-minute test.

[0273] Results: The results of the flame spread, smoke and temperature tests are shown in FIGS. 9A-9B. FIG. 9C shows the ambient temperature of the internal tube furnace for reference. Similar results were obtained for the 10 minutes and 20 minutes extended tests.

[0274] A flame spread of 0 and a smoke developed of 0 was observed when tested in accordance to Section 2303.2 of 2021 International Building Code, referencing ASTM E84-18b, Extended 20 minutes, and ASTM E2768-11-(2018) the tested material resulted in a Class A during the first 10 minutes of the test and achieved a flame spread of less than 0 feet from the centerline of the burners during the 30-minute flame exposure. Thus, the product met the above specification for Ignition Resistant Material.

4.4. Steady-State Thermal Transmission Property Test (Heat Flow Meter Test) per ASTM C518-21

[0275] The cementitious material (C518-B) samples (13.5 W13.5 L1 Thick) having one smooth side and one rough side were tested under the conditions shown in Table 12. Briefly, the test sample was placed between a hot plate and cold plate. Heat flux transducers are located between the test sample and the plate. Tests were performed using a ATI12 Meter, which was calibrated prior to use using a NIST Standard Reference Material 1450d, Fibrous Glass Board (Serial Number 357), which has an SRM Thermal Conductance (C) of 0.228 Btu/hr.Math.ft.sup.2 F. The test was allowed to procced until a thermal equilibrium was reached. The electromagnetic field (EMF) output of the transducers, mean temperature of the test sample and the temperature drop across the test sample were measured at multiple intervals and used to calculate the thermal conductivity.

[0276] Results: The results of the heat flow meter test are shown in Tables 15 and 16 and FIGS. 10A-10C. The results of this test show that the two test samples of prepared using the geopolymer formulations disclosed herein achieved a thermal resistivity of 2.70 (m.Math.K/W) and 2.77 (m.Math.K/W). For comparison, Portland cement-based products have thermal resistivities in the range of 0.6 to 1.0 (m.Math.K/W). Thus, building materials prepared using the disclosed geopolymer formulations thus have at least 250% higher thermal resistivity than Portland cement-based products.

Example 5. Fire Burning Properties of the Cured Geopolymer Product (Formulation A)

[0277] Test Apparatus: Testing was performed on a pilot-scale fire burning apparatus (70-inch60-inch52-inch, FIG. 11A) following the time temperature fire exposure as outlined in ASTM E119 and CAN/ULC-S101. Temperatures within the furnace were monitored using four thermocouples. The temperatures are controlled by adjusting fuel to the furnace burners to conform to the time/temperature curve specified by the test standards. Temperature measurements are recorded by an Agilent 34970A data acquisition unit (ID #ConeDAQ02) in communication with a computer for graphical display and storage. Interior and Unexposed temperatures were monitored by thermocouples (TCs) placed at locations as shown in FIG. 11B. The temperatures were recorded continuously for the duration of the test, and the temperature rise data are provided graphically in FIGS. 12A-12C.

[0278] Test Sample and Protocol: A pilot scale wall assembly comprising the cured geopolymer product (1-inch thick), 0.5-inch oriented strand board (OSB) with chicken wire, 24 wood framing, fiberglass insulation and -inch Type X gypsum board was used for this study (Table 17). The wall assembly was mounted in a vertical orientation, into a steel frame specimen holder. The specimen holder was then rolled up to the furnace and secured by chain and straps to the furnace opening. A ceramic fiber gasket was used to maintain an airtight seal between the furnace and the wall assembly. One pressure tap was installed through the back wall of the test furnace. The pressure tap was attached and monitored by a Setra model 264 pressure transducer (ID #Pressure T2). The furnace pressure was controlled by adjusting a damper in the furnace exhaust stack and monitored throughout the tests. Prior to the fire endurance test the test assemblies were moved into position in front of the furnace and the pilot burners were ignited. The fire endurance test was initiated after igniting the burners. The temperature inside the furnace was controlled to follow the standard time/temperature curve within the limits described in the test standards. The wall assembly was evaluated for a 1-hour fire-resistance rating.

Exterior Surface: Cured geopolymer product: BA/Form A/HDS-1, Chicken Wire, Building Paper. Dimensions: 80-inch wide by 75-inch high by 5.63-inch thick. Framing: Nominal 2-inch 4-inch wood framing spaced 16-inch on center. Panel Sheathing: -inch OSB. Insulation: R14 fiberglass insulation. Interior Panel: -inch-thick Type X gypsum board fastened using no. 6 1 -inch coarse thread drywall screws spaced 12-inch on center. Interior Finish: General purpose pre-mixed drywall compound and 2-inch (51 mm) paper tape was used on the joints and drywall compound was placed over the screws.

[0279] Results: A summary of the qualitative test results is shown in Table 18. FIG. 13A shows the surface 1300 before exposure to the flame and FIG. 13B shows the surface 1350 after exposure to the flame. No flaming occurred on the unexposed face 1360 (FIG. 13C) of the wall assembly, and no through penetrations or openings were observed during the fire tests. The maximum allowable single point temperature limit of 325 F. (180 C.) over the initial and the maximum average temperature limit of 250 F. (140 C.) over initial were not reached for the duration of the fire endurance test. The wall assembly was found to meet the fire endurance requirements of the test standards for a 1-hour fire resistance rating.
