Innovative nanomodified fine-grained concrete for additive technologies.

The successful transformation of modern nanotechnological approaches in building materials science into commercial products and their introduction to the market for commercial use is ensured by the choice of an affordable nanomodifier and the widespread use of regional raw materials for building mixtures. The paper substantiates the use of a mechanically activated cement-sand composition as a nano-modifying additive in a concrete mixture for formless molding of building structures by the method of additive technologies.
