The new structure of raw materials is developed for production of a ceramic brick with use of the inorganic waste which is formed at water treatment on combined heat and power plants. The chemical composition of the calcinated ferriferous waste is defined. The content of heavy metals decided on the help of the nuclear and issue analysis. On JSC «Obolsky Ceramic Plant» the pilot batch of a ceramic brick is made. Tests of the ceramic brick containing from 5 to 25 % (masses are carried out to laboratories.) ferriferous waste instead of clay. It is established that the brick containing the inorganic calcinated waste conforms to requirements of STB 1160–99 «A brick and stones ceramic. Specifications». Influence of the contents in initial raw materials of ferriferous inorganic waste on the structurization processes happening in a ceramic brick is investigated. Influence of particle size distribution of waste on process of formation of products is studied.
