Relationship of Properties, Phase Composition, and Microstructure of Clinker Brick

Clinker brick was obtained on the basis of polymineral raw materials, including low-melting and refractory clays, loams, and granitoid screenings in the plastic method of manufacturing. The interrelation of the physical and chemical properties of products was determined as a function of the mass content of the components and the oxide composition of the charge, and the optimal temperature_time regimes of firing were determined — 1150 ± 5°C with exposure of 4 h at an optimal temperature. The data obtained on the oxide and mineral composition make it possible to predict the composition of the charge for producing clinker brick, the heat-treatment regimes, and the properties of the products.
