Influence of polyfunctional nanomodificators on the microstructure of concrete composites of high strength and density

Abstract

The patterns of formation of highly functional concretes structure, which consist in formation of an ordered, low-porous, fine-crystalline microstructure of cementitious matrix, in particular due to pozzolanic reactions of the non-clinker part of the binder with formation of an additional amount of low-basic hydrocarbons, are investigated.
