Gypsum concrete is light weight and fire resistant.

The brand name Gyp-Crete, a Maxxon Corporation trademark, has come into general use as a term for gypsum concrete by construction professionals and architects.

A 1.5 inch slab of gypsum concrete weighs 13 pounds per square foot versus 18 pounds per square foot for regular concrete.

Gypsum concrete is a building material used as a floor underlayment used in wood-frame and concrete construction for fire ratings, sound reduction, radiant heating, and floor leveling.
