The Effect of Sodium Formate on Concrete Hardening at Low Temperatures

ABSTRACT

We consider the problems of doing concrete work in the winter. Selected one of the ways to solve it – the use of antifreeze additive. The results of experimental studies of the effect of sodium formate for concrete hardening at low temperatures. With the help of mathematical and statistical methods of the experiment of the first order (the number of factor 3) to obtain an equation describing the process, the predictive strength of the concrete. The factors were taken charge of cement, curing temperature and fuel additive sodium formate. This equation takes into account the technologist these factors in the design of concrete with the use of the additive.
