The paper presents the study of the influence of complex additives on strength properties of cement concrete. Complex nanostructured additives from various components containing nanosized particles received through the laboratory study are used in experiments. High strength of fine-grained concrete is obtained. The optimum concentration of additives of nanostructured mineral components together with superplasticizer thus ensuring high strength is established. The study shows that the developed nanostructured complex additives increase early and design strength, improve mobility and can be used in the production of self-compacting construction concrete.
