Abstract

The influence of the synthesized nanometric hydrated calcium silicate on acceleration of early hardening of cement concrete in normal conditions and when steaming is examined in the article. It is shown that at the dosage of the crystallization centers of 1 % of the cement mass there is the acceleration of early hardening from several hours to 1?2 days at old generation concrete and at the reactive powder and powder activated fine-grained concrete of new generation. Nanometric hydrated calcium silicate are characterized as the power- and heat-saving additive in industrial technology of concrete and reinforced concrete and in monolithic construction.
