The importance of inert mineral additives for the development of modern concrete technology is considered. The results of a study of the influence of the dosage of limestone powder on the consistency and strength of fine-grained concrete with different ratios of its components are presented. It was established that in concretes with a high content of superplasticizer, the proportion of mineral additives in mixed cement is the main technological factor in controlling the strength characteristics of concrete.
