Present invention teaches using MGO (magnesium oxide) materials, with the formula of the ingredients as disclosed to create a paste of slurry mixture. A molding and curing process is done by placing a layer of alkaline fiber in a mold with repeated application of the slurry mixture. Additional surface treatment, after hardening/curing, can be done to create surface decorative features, using environmentally friendly water-based coating, to suit clients’ specification.

The present invention relates in part to an alkali-silica reaction mitigation admixture comprising an organic or inorganic salt that provides an aluminum, calcium, magnesium, or iron cation. The present invention also relates to a method of mitigating the alkali-silica reaction in a concrete product. The invention is further related to kits comprising the alkali-silica mitigation admixture and an instruction booklet.

Described herein is a polyion complex, including x mol of polycations and y mol of polyanions, x and y being integers from the range of 1 to 100 and x being ≤y or x being ≥y. Also described herein is a method for producing a polyion complex, an aqueous solution of a polyion complex obtained using the method, and the aqueous solution of a polyion complex itself. Also described herein is a method of using a polyion complex to modify the surface of polymer fibers and/or carbon fibers and a method for modifying the surface of polymer fibers and/or carbon fibers using an aqueous solution of the polyion complex. Also described herein are surface-modified polymer fibers and/or carbon fibers obtained using the method, the surface-modified polymer fibers and/or carbon fibers themselves, methods of use thereof to produce fiber-modified construction materials, and a fiber-modified construction material including same.

Provided herein are compositions, methods, and systems comprising vaterite and magnesium oxide.

Provided herein are cementitious materials, for example, a crack-resistant cementitious mortar. The cementitious materials are a mixture of cement, at least one recycled fiber reinforcement material, a recycled aggregate material, and water. Also provided is a method for increasing the crack-resistance of a cementitious material by replacing the sand in a cement mortar with a recycled aggregate material and adding at least one recycled fiber reinforcement material and a volume of water.
