A study of the properties of lightweight geopolymer materials (GM) based on refractory technogenic waste of aluminosilicates has been carried out. The effect of the ratio of oxides SiO 2 and Al 2 O 3 in the compositions of GM on the physical and mechanical properties of GM has been investigated. It was found that a decrease in the ratio SiO 2 / Al 2 O 3 in the composition of GM leads to an increase in density and strength, and a decrease in water absorption of samples after exposure. After firing at temperatures of 800 and 1000 & # 176; C, the strength of the samples is the higher, the lower the ratio of SiO 2 / Al 2 O 3 in the composition ... The heat resistance of samples with a high ratio SiO 2 / Al 2 O 3 is four thermal cycles, and with a low ratio, more than seven cycles
