Conclusions
The addition of 20% finely ground kyanite-sillimanite concentrate or electrocorundum slurry to the aluminosilicate concretes based on kaolin chamotte with phosphate and alkali-silicate bonds contributes to the formation in the body, at high temperatures, of a ceramic bond with a well developed mullite phase, which improves the thermal properties of the material.
The introduction of the same quantities of kyanite-sillimanite to the concretes based on aluminous cement somewhat impairs their thermal properties.
The use of sillimanite concentrate containing large quantities of impurities (iron oxides and fusible minerals) impairs the thermal properties of the aluminosilicate concrete.
The use in the composition of refractory concrete of kyanite-sillimanite concentrate in the natural grain state, not requiring additional grinding and thermal processing, or the use of waste from the abrasive industry, is economically desirable, and can be recommended for use in industry.
