Sludge of the Fuel-Energy and Oil-Producing Complex in the Production of Wall Ceramic Products
The experience of using slime wastes in the production of wall ceramic bricks is considered. The results of the investigation of clayey raw materials in the deposits of the Western Orenburg region and technogenic wastes of the fuel-energy and oil-producing complex are analyzed with an analysis of their effect on the properties of wall ceramics: density, strength, and water absorption. Based on the results of the research, optimal compositions were developed using ash and slag wastes in a composition with aluminosilicate clay raw material - loam. The influence of drill cuttings with an increased content of calcium oxide on the composition and physical and mechanical properties of wall ceramics, the effect of a composition of low-grade local clay raw materials and drill cuttings on the formation of the structure and properties of ceramic materials is shown. The analysis of the volumes of formation of ash-and-slag wastes and drill cuttings is given, which makes it possible to introduce technogenic wastes into secondary production and to expand the mineral and raw materials base for the production of ceramic bricks.
