1. The heat-resistant cellular concrete on the base of aluminum-magnesium-phosphate binder and corundum
waste with an average density of 600-900 kg / m3 and working temperature of 1500-1600ºC was developed.
2. It was established that during heating of the developed compositions there are no any destructive effects. The
final products after heating to 1000 °C are stable refractory components. The phosphate cement stone
comprises mostly
