Abstract
An alkali metal silicate foam composition comprising preferably sodium silicate, cementing agent such as sodium silicofluoride, gelling agent such as linoleic acid and filler such as glass fiber mixed with water and blowing agent to provide foams having high strength, high water resistance and low shrinkage upon curing. Amides and halo-alcohols are used as gelling agents in preferred compositions for exceptional strength and water resistance. Vermiculite and perlite are preferred fillers for a low shrinkage foam composition.
