Ceramic wall materials occupy a leading position in the construction market due to their physico-mechanical, thermal properties, durability, environmental friendliness and architectural expressiveness. The industry of ceramic building materials is one of the most material and energy-intensive industries. In the total amount of fuel consumed in the construction complex, the costs for the production of ceramic bricks are 4.6%. Therefore, the rational use of fuel, raw materials and other material resources is becoming a decisive factor in the competitiveness of ceramic wall materials in the construction market. Coal ash is a by-product of the burning of mineral coal in thermal power plants. This residue is responsible for many environmental problems because it pollutes the soil, water and air. Therefore, it is important to find ways to reuse it. In this regard, the issue of using ash and slag waste from thermal power plants in the production of wall ceramic products becomes urgent. The aim of the master's thesis is to develop compositions and study the properties of a ceramic crock using ash waste from Thermal Power Station. The main results of the work: The influence of the Stahiment 2000 MZh30 superplasticizer on the strength and density of a ceramic crock from clays of the Osetka deposit was studied, the results on the physic-mechanical characteristics of a ceramic crock containing ash waste from the Belorussian Thermal Power Station Orekhovsk were obtained.
