Abstract
An extrudable composition is provided which is made up primarily of gypsum, a binder/rheology aid and water with a crumbly, semi-dry consistency. The extrudable composition described can be extruded through a die to provide a building product. Density can be minimized and strength optimized by using features of the composition and of the process.
