**5. Conclusions**

Based on the theoretical analysis of the basic models of the kinetics of heterogeneous processes of structure formation of cement-based materials, we proved that they are the subject and purpose of nanotechnological control. The possibilities of regulating the evolutionary route of formation of a solid substance for cement-based materials at the stages of phase nucleation, particle growth, their agglomeration, and spontaneous and self-organized structure formation are revealed. It is shown that in the evolution of the structure of cement-based materials at the nanoscale level, its nano-modification is determined by a set of controls. In this complex, one of the effective means is the use of nanoscale additives, which determine the direct nano-modification of structural elements at the level of individual crystals and crystalline intergrowth, in the zoning and clusterization of the microstructure.

It was experimentally shown that the use of nano-modifiers based on nanoscale SiO2 particles and carbon nanotubes determines the acceleration of hydration, hardening by 3–10 times, increasing the maximum values of the strength of cement-based materials by 1.5–2 times.
