INFLUENCE OF GRANULOMETRIC COMPOSITION OF AGGREGATES ON THE PROPERTIES OF CONCRETE AND MORTAR MIXTURES
The technological and operational properties of concrete and mortar mixtures are formed due to the correct consideration in their formulation of indicators such as the shape and nature of the surface of the grains, grain composition, intergranularvoidness, water demand and maximum particle size. Therefore, to design a benign composition, it is necessary to study the effect of particle size distribution of small and large aggregates on the basic properties of concrete and mortar mixtures. The goal is to optimize the particle size distribution of aggregates. The work was implemented as part of research on the fulfillment of scientific project No. 18-48-200001 “High-quality concrete with enhanced performance properties based on local natural and secondary raw materials,” which received support from the Russian Foundation for Fundamental Research (RFFR).
