Curing kinetics in the activated cement-water system

Abstract

The paper deals with the strength improvement in the cement-water system that generally leads to the improved performance of hydrated cement and concrete. After many years of experiments conducted by Russian and foreign experts, many ways to improve the strength of cement systems have been developed. The most efficient are various activation methods of either cement or water, which is then used as water of mixing for cements. This work studies the structure formation processes in the activated cement-water system, which are still less investigated. Cement is activated through its dispersion in a planetary mill, and water is activated by a constant magnetic field with 0.1 T flux density. It is found that the strength of the cement-water system increases by 38% in comparison with the untreated test samples.
