Freeze-thaw resistance of steam cured concrete on blastfurnace cement

The speed of destruction of concrete under cyclic freezing is connected with the structure of hydrated phase of a hardened cement paste. On the example of steam cured concrete on blasfurnace cement the capacity of such concrete to relax the tension, which is provided by the stability of gelatin phases and contributes to the increase of freeze-thaw resistance of concrete, is demonstrated.
