The paper describes the role of inert mineral additives in concrete technology. It was found that inert mineral additives are expediently use together with superplasticizers for the preparation of concrete mixtures with high workability at low cement consumption. It was shown that the negative effect of inert additives on strength decreases with a decrease in the water-cement ratio due to an increase in the proportion of cement hydration products and a reduction in the pore volume in a cement stone prepared with the use of inert mineral additives. There was established that the most promising direction of using these materials is the production of high-fluidity and self-compacting concretes of low and medium class with high frost resistance, water resistance and corrosion resistance
