Abstract
This invention provides cellular clay compositions which are dimensionally stable at 1000.degree.F. and higher, and which have a controlled pore structure that enhances the strength, durability and insulating properties of the compositions.
Claims12
A fired clay product composed of a rigid cellular mass having a bulk density in the range from about 10 to about 105 PCF obtained by mixing, foaming and firing a composition comprising about 20 to about 95 parts of clay, about 4 to about 35 parts of hydraulic cement, about 0.2 to about 30 parts of inert particulate lamellar foam stabilizer, from 0 up to about 76 parts of inert solid material, about 21 to about 70 parts of water, and a gas generating agent, said parts being by weight of the dry ingredients, all of the foaming action having occurred between cessation of said mixing and about 10 minutes thereafter.
A composition to be foamed comprising about 20 to about 95 parts of clay, about 4 to about 35 parts of hydraulic cement, about 0.2 to about 30 parts of inert particulate lamellar foam stabilizer, from 0 up to about 76 parts of inert solid material, and a gas generating agent, said parts being by weight per 100 parts of the dry ingredients.
