The scientific basis of the solution to the applied tasks of concrete technology through the use of «nano» tools, which provide the organization of the heterogeneous process of cement hydration and hardening, has been characterized. It is shown that the introduction of nanoadditives enables the direct regulation of he processes of structure formation in cement systems at the nanolevel. The effectiveness of the use of «nano» tools has been proposed to evaluate by means of complex criteria characterizing quantitatively the change in the activation energy, the rate of the process and time of its completion τ, the size and power consumption of the technology E while ensuring quality levels specified by R. According to the criteria, the monitoring of the results of the research has been made. Moreover, the most effective nanomodifying admixtures of two types have been identified.

The new technical solutions including inventions in the area of nanotechnology and nanomaterials are efficiently applied in communal and housing services as well as in construction and other joint fields. The invention «Protection system of urban housing and the method to build it (RU 2604933)» refers to construction including environmental structures and can be used to protect cities, objects of national economy from destruction, floods and other types of natural and antropogenic disasters. Reinforcement of basements of city buildings is performed with barrels with fillers and flexible dampener-ties that receive natural and antropogenic impacts thus providing safety, including ecological one, for urban housing.
