The article presents the results of scientific and experimental work on establishing the basic consistency patterns of changes in the physical and me-
chanical properties of granular samples of ceramic road material depending on the dispersion of slag in the firing temperature range of 950-1000°C . Loam from the Atyrau deposit and blast-furnace granulated slag «ArselorMittal Temirtau were selected as the object of study. According to the results of the analytical review of the works of domestic and foreign scientists, the urgency of using large-tonnage industrial wastes and easily accessible natural local resources that provide resource-saving and environmental efficiency of road and industrial-civil construction has been established. The analysis of the changes in the physical and mechanical properties of the ceramic mass revealed that finely dispersed granulated slag powders intensify the sintering process in compositions with clay minerals under high temperatures. A comparative analysis shows that the increase in the strength of samples upon compression in a cylinder at a calcination temperature of 1000°C and having a dispersion of granular slag passing through a 0.315 sieve
is almost 2 times.
Keywords: grinding, ceramic road material, firing temperature, ceramic composition, clay soil, granular blast furnace slag.
