Impermeability and frost resistance of concrete with an antifreeze additive-ammonia water

Kuz’min, E. D. / Virskaya, V. V. / Kruglov, V. A.

Conclusions 1. Concrete mixed with ammonia water and cured under a negative temperature has at an early age a higher impermeability than ordinary concrete without additives. 2. The presence of up to 60% ice in concrete cured under a negative temperature does not lessen the physical and mechanical properties in comparison with ordinary concrete. Partial ice formation (25–30% of the liquid phase) promotes a considerable increase in strength of concrete and its frost resistance.
