The influence of alumocalcium sludge on the physical, mechanical and thermal properties of alumosilicate and high-alumina products of phosphate hardening intended for operation at temperatures up to 1500 °C. It was found that the use of alumocalcium sludge in the compositions of non-burning phosphate compositions helps to reduce the polymerization temperature and thus provides an earlier formation of rock-like phases that are not subject to hydration. Based on the obtained mathematical model, optimal non-burning compositions are developed that are not inferior to similar products in terms of physical, mechanical and thermal parameters, which provides an expansion of the range of applications of the raw material base.
