The paper analyzes the Russian and foreign research into the use of nonstandard raw materials in the production of constructional anorthite ceramics. The raw materials with different chemical composition are investigated. It is shown that the use of nonstandard raw materials in the ceramic mixture makes it possible to obtain constructional products with 43.1 MPa compressive strength, 2150 kg/m3 density, about 7 % water absorption and frost resistance that meets the requirements of regulatory documents. The physical and mechanical properties are obtained due to the anorthite phase containing in the composition of end ceramic products, which is confirmed by the X-ray phase and microscopic analyses.
