摘要:The article considers the aspects related to initial formation of the structures in concretes containing nano-additives that significantly influence the type of newgrowths and their concentration during the cement hydration. The article depicts the role of the aggregate in formation of the contact zone structure between the cement stone and the aggregate, which mainly consists of ettringite and portlandite. Mathematical models of the cement stone hydrational hardening kinetics and its performance properties have been obtained.
