Originální abstrakt

Thermal diffusivity, specific heat capacity and linear thermal expansion coefficient of a lightweight composite with alkali-activated aluminosilicate binder and heat-resistant aggregate mixture of expanded vermiculite and electrical porcelain are measured in a wide temperature range. Experimental results show that the studied material has good prerequisites for high-temperature applications. The apparent thermal diffusivity at one-sided heating is significantly lower than at room temperature, and decreases for temperatures higher than 400 C. The effective specific heat capacity at elevated temperatures increases with temperature in almost the whole analyzed temperature range. The linear thermal expansion coefficient is substantially lower compared with common cement-based composites.
