Abstract
A cotton reinforced, cementitious, hydrated product is made by combining on a dry basis between about 25 and about 75 wt. % Portland cement, between about 1 and about 15 wt. % cotton fiber, between about 3 and about 30 wt. % inorganic filler and preferably between about 10 and about 40 wt. % silica with water to form an aqueous slurry. The slurry is formed into desired shapes such as sheets or slabs and cured by autoclaving to produce the desired product.
