In the vast landscape of industrial chemicals, Calcium Sulfate Dihydrate (CAS 10101-41-4), commonly known as gypsum, stands out as a fundamental building block for numerous construction materials. Its unique chemical and physical properties make it an indispensable raw material for manufacturers of cement, plasters, and drywall, significantly influencing the performance and durability of these products.

One of the most significant applications of calcium sulfate dihydrate in the construction industry is its use as a retarder in Portland cement manufacturing. When cement is mixed with water, it undergoes a complex hydration process. Adding calcium sulfate dihydrate controls the rate of this hydration, particularly the reaction of tricalcium aluminate (C3A). This control prevents flash setting, allowing sufficient time for the cement to be mixed, transported, and placed before it hardens. Without this crucial additive, cement would become unworkable almost immediately after mixing. Manufacturers looking to buy industrial-grade calcium sulfate dihydrate for cement production prioritize consistent quality to ensure predictable setting times.

Beyond cement, calcium sulfate dihydrate is the primary component of plaster of Paris, formed by heating gypsum to remove some of its water of crystallization (forming calcium sulfate hemihydrate). This material is widely used for creating architectural moldings, decorative elements, and for plastering interior walls and ceilings due to its smooth finish and workability. The ability to buy calcium sulfate in the correct form is essential for achieving desired aesthetic and functional results in plaster applications.

Furthermore, drywall, or gypsum board, relies on calcium sulfate dihydrate as its core material. The gypsum core is sandwiched between two layers of paper, creating a lightweight yet strong panel ideal for interior wall and ceiling construction. Its inherent fire-resistant properties, due to the chemically bound water that is released as steam when exposed to heat, make drywall a critical safety component in modern buildings. The demand for industrial calcium sulfate for drywall production is substantial, requiring large-scale and consistent supply.
