The study of physical and mechanical properties of ceramic wall materials of the matrix structure from coal waste and iron ore beneficiation waste is presented. The results of the inves- tigation of the chemical, granulometric and mineralogical compositions of raw materials are given. In the factory conditions, a hollow ceramic brick of the size 1NF with dimensions of 65х120х250 mm was produced from granular charge based on technogenic raw materials (70–85% by weight). The products meet the requirements of GOST 530–2012 for the strength grade M100–200, for frost resistance F25, F50, for the class of medium density – 2. According to the thermal characteristics, the bricks belong to the group of inefficient prod- ucts and have an equivalent coefficient of thermal conductivity of the masonry more than 0.45 W/(m·°С). According to the specific effective activity of natural radionuclides, the prod- ucts belong to the first class and can be used without restrictions. It is established that there are no efflorescences on the surface of bricks from coal waste and their insignificant mani- festation with alternate moistening and drying in ceramic products from slagged iron ore. A chemical method for transferring sulphates to water-insoluble compounds is proposed to eliminate high temperatures.
