摘要：
Problem statement. Taking into consideration the effect of moisture conditions of concrete by introducing empirical coefficients which are not justified theoretically and experimentally does not provide physical understanding of the influence of concrete structure and its moisture conditions. Results and conclusions. It is suggested to differentiate the inflow of the gas mixture to concrete into effusion and diffusion components with respect to the diameter of capillaries. The expressions for estimation of their contribution to the general flow depending on moisture content are given.
