The article discusses the results of investigations on the influence of the stress state of concrete on its frost resistance. Particular attention is paid to the effect of low negative temperatures (up to minus 70oC) on the parametric levels of the stress-strain state areas during axial compression of structural heavy and light concretes of B30 and B40 compressive strength classes, in particular, on the lower (R0T) and upper (RνT) boundaries of the microcracking areas of these concretes. An assessment of the degree of influence on this process of the structural and technological characteristics of concrete was made. The results obtained can be used in the practice of reinforced concrete structures designing that will be operated in the harsh climate of the North-Eastern regions of Russia, the Far North and the coast of the Arctic shelf of the country.
