The application of engineering cementitious composites (ECC) – a specially developed class of cement-based material reinforced with fibers – allows to enhance the loading capacity, stability under static and dynamic influences, as well as durability of building structures due to controlled cracking process. The design of engineering cementitious composites is based on the concept of micromechanics, which includes the strength and energy criteria of deformation strengthening throughout the wide range from the macro- to the nanostructural level.

The article shows that one of the innovative ways of obtaining of High performance rapid-hardening concretes is the use of nanotechnology techniques related to the directed process of structure formation by modifying of nanoscale elements. The strategies for the implementation of nanotechnology in the manufacture of concrete - the adding of primary specially synthesized nanoscale components or direct synthesis of nanoscale objects in the space of material and on the boundary interface are analysed.
