Cellular glass ceramic materials on the basis of zeolitic rock

This paper presents the results of investigations referring to a low-temperature technology for the production of cellular granulated materials on the basis of zeolitic rock. Using zeolitic rock from two different Russian deposits porous granulated materials were produced at process temperatures below 900 °C. Dolomite and chalk were used as carbonate expanding agents. The obtained material possesses a compressive strength of 8.8–15.7 МPa, and a bulk density of 570–690 kg/m3.
