EFFECTIVE MEANS FOR REDUCTION OF AUTOGENOUS SHRINKAGE IN HIGH-STRENGTH CONCRETE
The necessity of internal curing during the hardening of high-strength concretes is shown. It has been determined that the partial replacement of microsilica with addition of finely dispersed, in particular zeolite reduces the autogenous shrinkage strain, while there is no reduction in the strength characteristics of concrete. This technology can enable collection of low-defect, reliable and durable building structures made of concrete and reinforced concrete.
