Lightweight phosphate refractory concrete based on a binder made from industrial aluminosilicate raw materials

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 obtaining 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 aluminophosphate binder is not inferior to cellular materials based on known aluminophosphate binders.
