Comprehensive Neutralization of Fuel Energy Waste in the Production of Calcining Efficient Building Materials

The development of technologies for producing ceramic building materials based on energy waste fuels is associated with the study and identification of their valuable properties, which ensure the possibility of producing wares with high performance characteristics. The physicochemical and technological properties of ash and slag and high-calcium waste from the Novocherkassk Regional Power Station have been studied and their influence during high-temperature treatment on the basic properties of ceramic bricks - porosity, density, strength, depending on the chemical and mineralogical composition of the clay raw material has been established. The use of the mathematical planning method using a Scheffe lattice plan of incomplete 3rd order made it possible to determine the areas of structures formation with different properties depending on the content of waste and clay raw materials and to establish the area of tailored compositions, which can significantly reduce the number of experiments performed. Studies of the phase composition have shown that the strength properties of ceramics are ensured by the formation of new crystalline phases
