ABSTRACT:
An inorganic cement mixture, capable of being thermally foamed in situ, consists essentially by weight of 8-20% of crystalline hydraulic cement, 22-35% of a hydraulic cement in the form of a glass powder, and 45-70% quaternary ammonium silicate solution. The mixture can be set as a cement and thermally foamed to unite two bodies and serve as a spacer and support to maintain them in spaced relation.
