STUDY OF PHYSICAL AND MECHANICAL PROPERTIES OF CERAMIC CONSTRUCTION MATERIALS BASED ON OIL PRODUCTION WASTE

The main objective of the research is to develop technological solutions aimed at reducing the environmental impact through safe disposal of oil industry waste, as well as increasing the economic efficiency of ceramic building materials production. Inclusion of oil-containing waste in ceramic mixtures can help improve their technological properties, which in turn leads to a reduction in energy costs and an increase in production profitability. In addition, the use of such waste in building ceramics contributes to a closed production cycle, which corresponds to the principles of sustainable development and a circular economy. Drilling mud from the Slavyanskoye deposit in combination with medium-plastic clay from the Vladimirovskoye deposit in the Southern Federal District was chosen as the main raw material for obtaining ceramic materials for construction purposes. The work investigated the physical and mechanical properties (density, water absorption, strength, frost resistance) of ceramic building materials based on oil production waste. The results of the study showed that with a drill mud content of 60 % in the mixture, the material has M250 grade strength, F75 grade frost resistance, an average density of 2200 kg/m3, and water absorption of 12.00 %. It has been shown that the presence of drilling mud in the raw material mixture allows one to regulate the properties of the resulting material, as well as to reduce the content of clay, a natural non-renewable raw material.
