TIME FACTOR FOR SET OF CRITICAL STRENGTH OF WINTER CONCRETE

Abstract

This paper assesses the technological features of winter concreting. In order to predict the cooling time to the set of critical strength, the following are taken into consideration: surfacing module, initial and final temperature of concrete, specific heat capacity of concrete, outdoor temperature, type of concrete formwork. The additional costs of thermal insulation of concrete are considered by taking into account its heat release, thermal conductivity of heat of various formwork.
