Abstract

The destruction of cement stone at cyclic freezing is due to ice formation, change of hydrated phase structure, and leaching of Portlandite. The freeze-thaw resistance of concrete in water solutions of deicer depends on porosity parameters and on stability of the cement stone structure. The latter is provided by predominance of gel-like calcium hydrosilicates and a limited content of Portlandite.

Key words:

hydrated phases of cement stone; structure and frost salt resistance
