Binders for geopolymers, which include: a) not less than 30 w % of a mixture of at least two chemically different aluminosilicates, b) not less than 20 w % of Ordinary Portland cement, and c) 8-20 w % of a mixture of calcium sulfoaluminate cement or calcium aluminate cement with a source of calcium sulfate, wherein in the mixture the weight ratio of calcium sulfate to calcium sulfoaluminate and/or calcium aluminate is between 0.08-1.5, preferably 0.3-1.1, more preferably 0.6-1.1. Also, geopolymers using such binders as well as their use in various construction methods.

Multifunctional composite building materials, which are obtained by mixing nano silicon dioxide, nano titanium dioxide, nano aluminum oxide and nano zinc oxide with nano nickel-cobalt ferrite or nano nickel-zinc ferrite; surface active agent; air entrained agent such as diethanolamine lauryl sulphonate, protein extracts, pulp waste liquid, diatomite; kumgang medical stone; viscosifier such as hydroxyl ethyl cellulose and foam elimination agent such as tributylphosphoric acid ester or butanol in a certain ratio.

A system for forming a coating on a substrate is provided. The system includes a first mix having a cement, a filler, a defoamer, a cement retarder, a dispersing agent, or any combination thereof. The system additionally includes a second mix having a fatty acid derivative, a synthetic resin, one or more organosilicon compounds, a pigment, a thickener, or any combination thereof. A coating composition is formed by mixing the first and second mix together. Lastly, the system includes a spraying apparatus that applies a wet film to the substrate wherein the cured coating does not yield to wet-rubs and does not stain (effloresce) with cold distilled water.

Luminescent concrete compositions containing cement, fine aggregates such as sand, and a phosphor such as strontium aluminate. Glow-in-the-dark concrete products made therefrom and methods of producing such concrete products are also specified. The glow-in-the-dark concrete products demonstrate good mechanical strength (e.g. compressive strength) and skid resistance. The addition of phosphorescent strontium aluminate provides luminance that persists for up to 10 hours to the concrete products.

Sub-ambient daytime radiative cooling (SDRC) coating comprising: an alkali activated metakaolin, BaSO.sub.4, and silica nanospheres, wherein the alkali activated metakaolin is prepared by reaction of metakaolin with an alkali activator comprising waterglass and a strong base selected from the group consisting of LiOH, NaOH, KOH, Ca(OH).sub.2, Li.sub.2O Na.sub.2O, K.sub.2O, CaO, and a mixture thereof, a coating formulation comprising the same, and a method of preparation and use thereof.

A mortar mixture reduces crack formation by using microfibers in pool plasters in order to increase flexural and compressive strength. A waterproof fiber reinforced mortar mixture reduces crack formation by increasing the flexural and compressive strength of pool plasters. By means of the fiber reinforced mortar mixture, workmanship errors (water added more than required due to weighing the material wrong, surface finishing, etc.) and adverse effects due to the external environment (extremely hot and/or windy weather) are minimized.

Geopolymer compositions, and methods of making and using the same are provided. Coatings and composite products prepared from geopolymer compositions are also provided.

No added formaldehyde (NAF) compositions and composite products are provided. Geopolymer-based compositions, composite products with improved fire retardant properties and methods of making and using the same are also provided.

Geopolymer-based fire retardant intumescent coating compositions, methods of making and using the same are provided. Wood composite products prepared from geopolymer-based fire retardant intumescent coating compositions are also provided.

The present disclosure describes modular blocks configured to give the appearance of natural or cut stone. An aesthetic coating composition may be applied to one or more surfaces of a block having a low-density, such as an insulating concrete form (ICF), to form an modular block having the appearance of cut stone. The aesthetic coating composition includes a binder component, such as a cementitious binder made from white Portland cement, or a polymer binder such as an acrylic binder, an aggregate component, such as a limestone aggregate component, and optionally an adhesive component. The aggregate component includes a fine sand portion and a coarse sand portion that effectively enable the appearance of cut stone after finishing of the aesthetic coating surface via sanding, polishing, sandblasting, acid etching, acid finishing, or exposed aggregate finishing.
