This paper reports the results of an investigation on changes of compounds of alkali-activated aluminosilicates materials at high temperatures. The mixtures for testing specimens were composed of fine ground granulated blast furnace slag and dried sodium silicate (water glass) of silicate modulus Ms = 2.07. The materials were tested after 200, 400, 600, 800, 1000 and 1200°C. The compounds formed at high temperatures were identified by X-ray diffraction analysis, thermal analysis and mercury porosimetry.
