ABSTRACT:
An improved process for the preparation of an expanded, water insoluble silicate aggregate. Anhydrous alkali metal silicate is hydrated in the presence of a curing agent, then is subjected to rapid thermal expansion. The process eliminates the use of liquid silicates, and the reaction is conducted in an essentially dry state. The expanded product has extremely low bulk density.
