Results of natural experiments on studying of influence of softeners and film-forming preparations on durability of concrete designs are described by their manufacture. Calculation of durability of cement concrete of plates PND is made on a new method of an estimation of a condition with the account influence of a climate of northern territories on a material of designs. Influence of changing parameters of a real climate of northern territories on concrete of designs promotes development micro- and maсro defects in concrete that leads to decrease in durability of designs or constructions. As it has been established, steaming of products leads to strengthening of firmness of concrete at influence on it of a climate, but promotes formation of defects of structure which under certain conditions can affect firmness of concrete. Use of the forced modes of steaming leads to accumulation of deficiency of structure of concrete to the influence beginning on it of a climate and can become defining in firmness maintenance.
