Hardening of dry construction mixes at subzero temperatures

The article describes the scientific and technical aspects of hardening of dry construction mixes at subzero temperatures. It highlights the role the hydraulic activity of cement, phase-mineralogical composition of clinker and content of hydraulic additives. It also considers the effect of antifreeze additives, aqueous dispersion of an organic polymer on the character of dry construction mixes.
A schematic representation is given of the hardening process of modified dry construction mixes. Recommendations are given on the development of their formulations.
