Original Abstract
Alkali-activated slag belongs to prospective materials in the field of fire protection because it exhibits remarkable high-temperature resistance. In this article, specific heat capacity, thermal diffusivity, and thermal conductivity of an alkali-activated slag with sand aggregates are studied as functions of temperature up to 1200 C. The experiments are performed during the material exposure to high temperatures. The irregularities observed on the measured dependences of specific heat capacity and thermal diffusivity on temperature are discussed using the results of DTA and X-ray diffraction analyses. The crystallization of akermanite is identified as the most important factor affecting the properties of the studied material in high-temperature range.
