Gypsum Wallboard Chemical Additives

Gypsum Wallboard Chemical Additives

Gypsum, unlike cement, is a physical structure rather than a chemical structure. The needle-like gypsum crystals form a network to give the board its physical integrity The crystals are closely interwoven, giving the core most of its wet strength. After drying, the frictional forces of these crystals increase the strength of the core.
