The industrial by-product ferrous sulfate heptahydrate (FeSO4.7H2O) produced in the production process of sulfuric acid titanium dioxide can reduce the water-soluble hexavalent chromium (Cr6+) in cement to trivalent chromium (Cr3+) and precipitate it in cement because ferrous sulfate has very strong reducibility in the air, so as to solve the problem of high hexavalent chromium (Cr6+) content in cement.

Fibers are an ideal ingredient for use in concrete and mortars as a method for improving these materials where they may otherwise have weaknesses. Concrete fibers reduce shrinkage crack formation and crack widths whilst also increasing performance in abrasion resistance and fire resistance. Improve load capacity and ductility and protection against freeze-thaw cycles.

Bentonite-cement slurry seepage prevention wall is a type of anti-seepage wall formed by pouring a slurry solution made from ordinary Portland cement, bentonite, and water into pre-drilled grooves, resulting in a wall with excellent anti-seepage properties.

Desulfurization gypsum (English name desulfuration gypsum), also known as flue gas desulfurization gypsum, sulfur gypsum, or FGD gypsum, has the same main component as natural gypsum, being calcium sulfate dihydrate CaSO4·2H2O, with a content of ≥93%.
