Abstract

Water glass Na2O-SiO2 reacts in water solutions with Na2SiF6, yielding an amorphous SiO2 and NaF. This reaction, that is completed within a few days, causes setting and hardening of the system. Mortars made with this binder using appropriate fillers sustain temperatures of up to 900°C. At temperatures above 500°C, the hardened material converts gradually to tridymite quartz and sodium disilicate. Above 900°C, a sodium fluosilicate glass melt starts to be formed.
