Gypsum Concrete

Gypsum Concrete


a type of concrete, made with a base of gypsum binding materials (for the most part, structural gypsum).

This material is used in the production of gypsum concrete products. Rock mineral aggregates (primarily those with a porous and rough surface) and organic aggregates (such as wood shavings, sawdust, and chopped straw) are used in making gypsum concrete. Additives are introduced into gypsum concrete that retard its setting and also increase its resistance to water and the atmosphere. The strength of gypsum concrete depends on the same factors that determine the strength of ordinary cement concrete.
