LIGHTWEIGHT PHOSPHATE REFRACTORY CONCRETE BASED ON A BINDER MADE FROM INDUSTRIAL ALUMINOSILICATE RAW MATERIALS

Abstract

A modified aluminophosphate binder has been technogenically developed using aluminosilicate. Waste – a by-product of production firing of refractory clays from the Nizhne-Uvelskoye deposit – was used for obtain-ing the raw materials for the binder. Нeat-resistant phosphate aerated concrete was developed based on the modified aluminophosphate binder. Its density was 600–800 kg/m3 and the temperature of application about 1400–1450 °C. The main heat-resistant properties of aerated concrete were investigated and aerated concrete using a modified alumi-nophosphate binder is not inferior to cellular materials based on known aluminophosphate binders.
