The paper presents an overview of recent studies on producing expanded clay (light aggregates) using various wastes, such as bitumen emulsions, oily waste, sewage sludge, and ash. Data on their use in reinforced concrete, expanded clay concrete, foam concrete, asphalt concrete, and even chicken feed are also provided. The results of the work show the efficiency of using waste in the production of high-quality aggregates. Various wastes in producing light aggregates are becoming relevant for research. Our work aims to use oil slurry as a corrective and bloating agent in producing light aggregates. The authors propose the following raw materials for producing light aggregates: loam, oil slurry, and fine-grained sand. The quality indicators of porous aggregates were determined by standard methods according to GOST 9758-2012. Sophisticated methods of research of raw materials and finished products were used. Compositions of ceramic combinations of aggregates and the technological parameters for producing light aggregates based on loams modified with oil slurry and fine-grained sand have been developed. The studied microstructure of the obtained material based on loam modified with oil slurry and sand allowed the conclusion that the introduction of oil slurry, which contains organic components in the form of resins, naphthenes, and paraffins, had a significant impact on the formation of the porous structure of fillers. The process of bloating of aggregates occurs due to the build-up of the liquid melt of the ceramic mass during firing when the reducing medium intensifies the process of accumulation of the liquid phase. It has been established that the oil slurry content in the composition of the developed compositions lowers the firing temperature by 50-100°C, and the sintering interval is more than 50°C. The resulting lightweight filler has high strength characteristics and low thermal conductivity.
