Abstract

Water-containing inorganic waste materials, originally in loose form, and which contain water-soluble components capable of reacting with each other are mixed and then compacted at a pressure sufficient to reduce the space, volume between the particles of material, cause the reduced space volume to become filled with water and the reactive components to react.
