AbstractAbout AuthorsReferences
The efficiency of using the semi-product of chemical production, a soda-sulfate mix (SSM), containing compounds which are potentially able to accelerate the cement hardening, is shown. As a result of the conducted study, the synergism of impact of accelerating pairs, included in the composition of the complex additive (SSM and widely used ones), on the reduction of cement hardening time, development of plastic strength of the cement paste, temperature of cement paste hydration and kinetics of gain in strength of cement stone both in the first hours of hardening and on the 28th day, has been revealed.
