Original Abstract
The effect of thermal pre-treatment up to 1,200.C on the structure and properties of alkali-activated aluminosilicate material containing electrical porcelain filler is analyzed in this article. The material is found to have very good hightemperature resistance. The reasons for its positive response to high-temperature exposure are, on one hand, the formation and subsequent crystallization of akermanite, and on the another hand, melting of electrical porcelain filler in the alkali environment at about 1,150 C and its subsequent reaction with the porous matrix resulting in formation of ceramic bonds. The combination of these two positive effects complementing each other in the formation of a new structure is responsible for the structure compaction indicated by the sudden decrease in porosity and is manifested in quite remarkable improvement of mechanical properties.
