| Abstract. | Problem statement. The purpose of the study is to identify the features of the effect on the properties of cement stone of adding clays of different composition and roasting temperature to Portland cement. Results. This paper presents the results of studies of the influence of the composition and calcination temperature of clay additives, ground to 250 m2/kg on the properties of cement stone. The most significant increase in the properties of cement stone is achieved with the introduction of additives kaolin clay, obtained by thermo-activation at temperatures of 300 and 600 °C, and the addition of polymineral clay (without kaolin) by thermo-activation at a temperature of 400 °C. Conclusions. The significance of the results obtained for the construction industry lies in the fact that they allow us to conclude that it is possible to produce economically and technically effective additives to Portland cement based on common clay raw materials with relatively low energy consumption for their thermal activation and grinding. |
