Abstract
The present invention relates to methods of greenhouse gas emission reduction by utilizing methods of the present invention in the production of viscous mixtures by determining the relative ratios or percentages of certain characteristics or properties of viscous substances, wherein temperature and/or moisture content is a key determinant. The methods may utilize placement of passive Radio Frequency Identification (RFID) instrumentation into a slurry or existing viscous mixture of substances. The RFID then reads moisture and/or other physical properties of the substance, typically process parameters such as temperature and/or pH. The readings are queried using an interrogator to acquire the data wirelessly. As a planning step, it is necessary to correlate the data with a variety of specially-developed algorithms specific to a viscous mixture associated with a particular process. The acquired readings will then provide a user with instantaneous information which will be determinative of the degree of completeness or maintenance of a certain property of the process.

DETAILED DESCRIPTION OF THE INVENTION
(18) To promote an understanding of the principles of the present invention, descriptions of specific embodiments of the invention follow and specific language is used to describe the specific embodiments. It will nevertheless be understood that no limitation of the scope of the invention is intended by the use of specific language. Alterations, further modifications, and such further applications of the principles of the present invention discussed are contemplated as would normally occur to one ordinarily skilled in the art to which the invention pertains. In the figures, like reference numbers represent the same component.
(19) The discussion of the present inventive concept will be initiated with
(20)
(21) Temperature sensors may be utilized in one or more embodiments. Similarly, moisture content, pH, density and other sensors may be utilized either independently or in conjunction with temperature sensors. In some embodiments, temperature passive RFID sensors are utilized. In exemplary embodiment the sensor 4 is passive. Other embodiments of this inventive concept may be equipped with battery-powered, or locally-powered sensors 4. These are generally known as “active” tags and may operate at hundreds of meters from an RFID reader.
(22) In
(23) The concrete rebar 13, along with aggregate 14 typically found in concrete structures is also shown.
(24) In
(25)
(26)
(27)
(28) The interrogator 33 then stores and sends the data wirelessly to a storage location, typically to a Cloud 37 location. In some embodiments, the current conditions of the process may be transmitted by conventional electronic communication via a land-line or similar hard-wired connections. In
(29) The passive sensor 31 receives electrical power from the interrogator 33 and implements readings of physical properties of the viscous substance, including, but not limited to, moisture, temperature, pH or substance parameters. The sensor 31 then transmits, by radio wave 35, its readings back to the interrogator 33, shown in
(30) With the unique tag 31(a) of the sensor 31, precise readings can be correlated to the location of the sensor 31 within the viscous fluid, or perhaps the unique individual tags of multiple sensors within the fluid. The interrogator 33 may temporarily store, or transmit 36 the readings received from the sensor 31 to a cloud 37 data storage system, as shown in
(31) The data stored in the cloud 37 is maintained and made available, accessible, and interpretable by means of various algorithms 38.
(32) A specific algorithm or algorithms 38 translates the data given by the sensor 33 into a useable form depending on the specific process which takes place.
(33) Once the data is collected in the Cloud 37 data storage system and the appropriate algorithm 38 translates 39 the collected data, the information is sent to a final user or users (not shown) via appropriate communications means 40 and 40(a). Ultimate end users may acquire the transmitted data 39 by means of mobile phones 41 and desktop computers 42, respectively, shown in
(34) In
(35)
(36) A data collection period will be used for collection of results of temperature, moisture, and pH readings over specific times under varying conditions. The resultant rendering of the hardness and strength, or possibly a curing objective 97 of the substance can then be precisely indicated. All the data collected will be plotted until algorithmic graphs are created, as demonstrated with
(37) In
(38) In
(39) Again, using concrete as the representative substance, when the temperature may be high, there is still curing time left. Only when the moisture content is low and temperature is also relatively low, will the curing of the concrete be complete. Therefore, the moisture reading and temperature, once known, can be plotted and compared to previous data to determine the third variable, the compressive strength of concrete, which would be representative of the percentage of a complete curing process of concrete. Compressive strength could be in pounds per square inch, (psi) or it could be in Newtons per square millimeter (N/mm.sup.2).
(40)
(41) At process 80 an interrogator 81 provides power to the applicable sensor 82, which sensor 82 sends both its unique tag ID 84, and the reading 86 of moisture content 85 back to the interrogator 81. At process 90 an interrogator 91 provides power to the applicable sensor 92, which sensor 92 sends its unique tag ID 94, and its reading 96 of pH 79 back to the interrogator 91.
(42) The culmination and ratios of the above-described processes 60, 70, 80, and 90 all render a cumulative determination of the strength and hardness 97 of the viscous fluid which is being processed.
(43) The user(s), upon the receipt of usable moisture and related data such as temperature, pH, or other parameters, can then accurately determine the stage of the process being monitored.
(44) Over a period of time, when the appropriate stage or completion percentage 97 of a process is determined, the user can make better decisions about the specific process, without additional testing or other complicated, inefficient attempts at guessing.
(45) As noted above, concrete is one of the largest producers of carbon dioxide (CO.sub.2) and therefore greenhouse gases. The CO.sub.2 emission from the concrete production is directly proportional to the cement content used in the concrete mix; 900 kg of CO.sub.2 are emitted for the fabrication of every ton of cement, accounting for 88% of the emissions associated with the average concrete mix.
(46) By utilizing the methods and sensors taught herein that measure temperature and/or moisture that have a lower standard deviation than traditional concrete cylinder testing would reduce the (1) greenhouse gas emissions, and (2) cost of concrete.
(47) Herein, a standard deviation in concrete mix design is also referred to as a margin of safety requirement. Margin of safety requirements based on prior art methodologies, such as the ten percent guidelines are referred to herein as a standard margin of safety requirement. Such standard margin of safety requirement may also be based on other percentages or guidelines. In determining an improved standard deviation according to the present invention, a new, i.e., improved standard deviation is produced and results in an improved margin of safety requirement.
(48) There are approved standards, such as the Maturity Method, that allow the use of temperature sensors to approximate the early strength of concrete. The sensors could be probes, or other kind of sensors such as RFID tags. The RFID tags could be active or passive. In testing of passive RFID temperature sensors, the average standard deviation 1.5% (i.e., the improved standard deviation, and, thus, an improved margin of safety requirement). The current accepted standard deviation is 10% of the cylinder breaks (i.e., standard margin of safety requirement), but with RFID temperature sensors at a 1.5% standard deviation (a standard deviation reduction of 85%), the greenhouse gas emissions could be reduced by proportionately (via the improved margin of safety requirement). In some embodiment examples, the greenhouse gas emissions have been shown to be cut by 14%. By reducing the standard deviation of testing of concrete, there is a reduction of greenhouse gases and savings for the industry. By way of example, in one field test with a precast concrete company, one standard mix design is supposed to be 6000 psi after 28 days. Although accepted standards allowed them to have a 600 psi standard deviation (also referred to herein as standard margin of safety), their process is controlled to a 300-500 psi standard deviation, standard margin of safety. The company cannot have a break at less than 6000 psi, or it would be considered out of specification, i.e., failure.
(49) There are previously established Maturity Curve (ASTM C 1074) based on previous testing for the same concrete mix and same process and multiple tests.
(50)
(51) In accordance with testing of the present invention,
(52)
(53) Sigma (σ) of cylinder breaks=375×3=1125 psi
(54) If a 6000 psi break point is desired, then the mix design=7125 psi (6000+(375×3)).
(55) Since the standard deviation of the temperature sensors is reduced an average of 78%, the standard deviation goes from an average of 375.5 psi to 82.6 psi.
(56) The sigma (σ) of new cylinder breaks is thus 83×3=249 psi with the above-described method of testing the strength of concrete. The new design mix target is 6249 (6000+(249×3)) instead of 7125. This is a 12% reduction in the amount of over-designing. The net reduction of 876 psi, at a cost of +$0.01 (+/−15%) per increase of psi/Cubic yard is $8.70 per cubic yard. If a plant makes 100,000 cubic yards per year, the savings are about $870,000 per year.
(57) Even more importantly from an environmental perspective, is the reduction in CO.sub.2 concrete plant produces. In the example above, the plant produces 100,000 cubic yard of 7125 psi mix design to achieve 6000 psi. 1 CY is 1.8 Metric ton.
(58) The CO.sub.2 emission from the concrete production is directly proportional to the cement content used in the concrete mix; 900 kg of CO.sub.2 are emitted for the fabrication of every ton of cement, accounting for 88% of the emissions associated with the average concrete mix.
(59)
(60) The amount of cement in 100 lbs. per cubic yard of concrete is approximately the psi in thousand lbs. Therefore, for a sample of 700 lbs cement per cubic yard, the strength can be estimated at 7000 psi. If a plant was previously designing a mix for 7125 psi, the plant was consuming about 712 lbs. of cement per cubic card. If the new mix design is now 6249 psi because of the utilization of the herein methods, the standard of deviation is reduced, then the plant is using 625 lbs. of cement. This resulting 12% reduction of cement usage is also reducing the carbon footprint of the plant by 12%. If the plant was making 100,000 cubic yards of concrete of 7125 psi concrete, it was consuming 712 lbs. cement/cubic yard×100,000 cubic yards=71,200,000 lbs. of cement or 32,296 metric tons of cement. 900 kg of CO.sub.2 per ton of cement×32,296 metric tons=29 million kg of CO.sub.2. If instead the plant is making 6249 psi mix, then it's consuming 28,350 metric tons of cement which is the equivalent of 25.5 million kg of CO.sub.2. There is about a 4.5 million kgs. of CO.sub.2 reduction for the plant and environment.
(61) Thus, by reducing the amount of a key ingredient (i.e., cement in the case of concrete production, bitumen in the case of asphalt, etc.), by reducing the standard deviation necessary, a net reduction of greenhouse cases is realized. Similarly, a significant cost savings is realized through the reduction in cement utilized. Herein, reducing greenhouse gases and the cost savings realized by utilizing less cement while still meeting design parameters are two examples of benefits obtained by utilizing the presented methods and processes of the invention.
(62) In one embodiment of the present invention; a method is presented for realizing a benefit by reducing an amount of at least one key ingredient, such as cement, by utilizing a process for determination, at any point in time, the quality or phase of a specific physical property of a viscous substance, as the substance progresses through a stages of a particular process.
(63) In one example, the steps include (a) ascertaining a desired compressive strength requirement for a predetermined viscous substance in pounds per square inch (“psi”) as a minimum required psi;
(64) (b) calculating a standard margin of safety requirement of ten percent (though this percentage is variable) of the compressive strength requirement but wherein the standard margin of safety requirement is not less than 500 psi even if said compressive strength requirement is less than 5000 psi (this amount is similarly variable in other embodiments;
(65) (c) ascertaining a minimum quantity of a key ingredient in the viscous substance based on a sum of the compressive strength and the standard margin of safety requirement;
(66) (d) reviewing existing scientific tables to ascertain how much of a greenhouse gas is produced in creating a predetermined amount of the viscous substance based on the minimum quantity of the key ingredient;
(67) (e) preparing algorithms of compilations of stored data corresponding to historic data showing effects of temperature, time, moisture content, pH, and other variable conditions on physical properties of said viscous substance;
(68) (f) positioning the viscous substance within or upon a specific container or enclosure;
(69) (g) embedding sensors in an interior mass of the viscous substance;
(70) (h) obtaining periodic measurements, transmitted from the sensors, of the specific physical properties of the viscous substance, in sequential segments of time;
(71) (i) accessing the previously-prepared algorithms for direct comparison with the periodic measurements obtained from the sensors and thereby converting the obtained measurements into a rendering of a stage, or quality, of the specific physical property of the viscous substance;
(72) (j) transmitting a conversion of the quality of the specific physical property to a mobile phone, electronic storage device, or desktop computer of an end user;
(73) (k) utilizing steps (e) through (j) to produce a more accurate and appropriate improved margin of safety requirement wherein the improved margin of safety requirement is less than the standard margin of safety requirement.
(74) Thus, by lowering the margin of safety requirement (i.e., improved) to produce a batch of concrete, less key ingredient is utilized, a lower quantity of greenhouse gases is produced as it is directly proportional to the amount of the key ingredient utilized.
(75) Similarly, by lowering the margin of safety requirement (i.e., improved) to produce a batch of concrete, less key ingredient is utilized, a cost benefit is realized in producing the batch due to the reduced quantity of the key ingredient. Thus, the benefit is a cost savings in the total production without affecting the quality of the finished product.
(76) While the specification has been described in detail with respect to specific embodiments thereof, it will be appreciated that those skilled in the art, upon attaining an understanding of the foregoing, may readily conceive of alterations to, variations of, and equivalents to these embodiments.
