Abstract: It is established that a mixture of chamotte-kaolin dust can be an effective substitute for thermally activated kaolin as a hardener for liquid-glass fireclay binders. Studies have shown that chamotte-kaolin dust, when introduced into the composition of aluminosilicate liquid-glass binders, exhibits a structure-forming ability under normal hardening conditions. Drying of the binder samples leads to a significant increase in compressive strength. Statistical processing of the results of an experiment to optimize the characteristics of liquid glass introduced into the composition of refractory aluminosilicate binders based on chamotte-kaolin dust is performed. Statistical processing of experimental data showed that the optimal characteristics of liquid glass in aluminum-silicate binders are: silicate modulus in the range of 1.0–1.5, and density from 1.25 to 1.30 g/cm3.
Keywords: sodium silicate, refractory binders, liquid glass, density, silicate module, chamotte-kaolin dust.
