Abstract
Industrial studies of the quality indicators of concrete mixtures (workability, water separation, mortar separation) and concretes (strength, uniformity of concrete in strength) have been carried out, depending on the characteristics of the filler used. The influence of fractionated and non-fractionated coarse aggregate on the properties of concrete mixtures and concretes was analyzed. It was confirmed that the use of fractionated coarse aggregate improves the quality indicators of concrete mixtures and concretes.
