ASPECTS OF RELIABILITY AND SAFETY ASSURANCE OF CONCRETE WORKS IN WINTER CONDITIONS

Abstract

The article analyses the topical question about the desired speed of concrete strength development assurance in winter conditions and the possibility of monolithic structures early loading in reliability and safety assurance. Having analyzed the experience of various methods of concrete temperaturemaintaining the authors studied the process of concrete strength development at temperaturesdifferent from normal. The multivariateregression analysis and regression models were built based on the dependence of modified concrete compression strength on time and temperature of hardening. The articleprovides the equations of multiple regression.
