Project objective. Identification the mechanism of interaction of nano-dispersed components in the structure of concrete on the basis of studying the impact of the degree of dispersion nano-modifying additive and its composition on the properties of concrete as a heterogeneous system.

Project objective. Use as a mineral admixture of different materials of anthropogenic origin greatly limits the possibility of obtaining high energy efficient concrete. Man-made materials allow to obtain significant savings in the production of concrete, but obtaining high strength concrete involves using multicomponent mixtures in which simultaneously several alternative mechanisms of formation of strength and structural matrices are used. Investigation of features of formation of structural bonds due to the use of nano-dispersed components will let us know about new properties of mono-, di - and multicomponent mixtures in which the feedstock, as a result of the nanoscale ultrafine grinding, will receive other, higher performance of existing properties. Studies of a simultaneous formation of several carrier matrices in a nano-modified structure of the concrete body, as well as their interaction and influence on the structural strength of the concrete will let us determine the possibility of further increase in the strength of high-strength concretes.

Special scientific and practical interest makes study of parallel existing matrices which provide an increase in the aggregate strength of the heterogeneous structure of concrete as a result of its modification with nanoadditives.
