In the article, as a solution to the problem of deep drilling in salt-bearing sediments, the use of a grouting chloride-resistant solution based on a sulfur composite material is presented. Sulfur is resistant to aggressive media (solutions of acids and salts), water resistance, which indicates the possibility of obtaining chemically and water-resistant building materials based on it. Modification of silica gel with aluminum chloride was carried out by mixing reagents by heating at various temperatures from 200 to 500°C with the ratio of astringent:filler is 1:1 and 1:1.5. An increase in the content of aluminum chloride to 5–8 % at a temperature of 200–400°C increases the strength slightly. An increase in the modification temperature above 500°C does not lead to a qualitative improvement in the strength properties of the composition, which is probably due to the sintering of silica gel and a change in its crystal structure. With an increase in the amount of modifying aluminum chloride additive, the water absorption of samples continuously increases at any temperature of preliminary heat treatment. The optimal ratio of binder to filler is 1:1 at a modification temperature of 500°C. Samples prepared according to the proposed formulation with an optimal ratio of components have a high coefficient of resistance to HCl, H2 SO4, CaCl2, NaCl, MgSO4 solutions, high impact strength (52 MPa), frost resistance (240 cycles) and density (1,790 g/cm3).
