The work is devoted to the processing of fly ash wastes obtained from coal combustion. Based on the non-magnetic fraction of fly ash (its particle size of 0-50 μm), an aluminosilicate glue or liquid glass as a cementing component has been obtained. It was represented by a number of silicate modules (SiO2/Me2O molar ratios): 2, 2.5 and 3 (for three different formulations). The shear deformation tests for glued plates with glues of various silicate modules have been carried out. The shear stresses for the samples with silicate modules of 2.0, 2.5, 3.0 were equal to 48, 66 and 34 kPa, respectively. These results suggest that during the production of aluminosilicate glue, the silicate module of 2.5 is more favored for providing the strongest bond between ceramic tiles.
