Control for concrete characteristics under winter conditions

The estimate of the requirements for concrete of monolithic structures, ripen under winter conditions is given. Such important characteristics as concrete strength, its rate of cooling, temperature difference between the outside air and concrete at stripping, temperature differential across the concrete section are considered. A critical analysis of the normalized values of concrete strength is given; and recommendations for their correction are highlighted. Theoretically proved comments on the effective way to control the strength of concrete are specified. The solution to control favourable thermal stress of concrete in the structure is performed.
