摘要：This paper addresses the prospects of recycling waste from oil and gas extraction in order to manufacture building materials. The principal possibility has been established to apply the examined samples of drilling sludge as the basic raw material and a mineral additive in the compositions of masses to produce wall ceramics with the required consumer properties.The main technological parameters for obtaining wall ceramics using the samples of gas extraction waste have been investigated. The formulations for ceramic masses have been developed applying fusible medium-sintered loam and drilling sludge in the amount of 20–80?% by weight. The properties of the obtained ceramic samples containing clay and high-carbonate drilling sludges have been analyzed. It has been found that increasing the amount of drilling sludge in the samples by 20?% to 80?% leads to a decrease in the density, strength, and an increase in the water absorption of the samples, which affects the quality of ceramics and the possibility of its practical use. We have established the regularities of change in the properties of the wall materials samples depending on the amount of the examined drilling sludge.The optimal number of drilling sludge samples for the manufacture of wall ceramics with the norm-compliant properties has been determined. It has been found that it is possible to use clay drilling sludge (20?80?%) in the composition with fusible loam in order to obtain frost-resistant ceramic materials whose water absorption is at the level of 12?%, of grade M 125?M 175. Adding high carbonate sludge to fusible loam in the amount of 20?% makes it possible to receive frost-resistant ceramic materials of grade M 75, in the amount of 40?% ? of grade M 100.
