The possibility of eliminating the alkali-silicon reaction (ASR-interaction) in foam glass due to the crystallization of the glass is considered. It was found that devitrite (Na 2 Ca 3 Si 6 O 16 ), octahedral phase (Na 4 CaSi 3 O 9 ) and cristobalite-tridymite modifications of SiO2. The binary glass-crystalline composition of the foam shows a significant reduction in ASR interaction. Slab glass foam crystallite (? Penosital ??) can be glued, plastering with a cement-sand mortar, covered with finishing polymer plasters. Granular foam can be successfully added as a lightweight filler in concrete without destroying it.
