Description	A lightweight composite material with alkali-activated aluminosilicate binder is investigated. The intended use of this material is the high-temperature applications, such as the fire-protecting layers for Portland-cement based structures. Therefore, a heat-resistant mixture of expanded vermiculite and electrical porcelain is used as aggregates. Basic physical characteristics, mechanical properties and waterand water vapor transport properties are studied as functions of previous heat treatment up to 1200 C. Experimental results show that the studied material has very good high-temperature properties which are quite superior to Portland-cement concrete. The open porosity increases only up to 7% between room temperature and 1000 C. The material keeps 35% of its original compressive strength and 66% of its flexural strength even in the worst case of 800 C pre-heating. After pre-heating to 1200 C the compressive strength is found 30% higher and flexural strength three and-half times higher than in the re A lightweight composite material with alkali-activated aluminosilicate binder is investigated.
