Freezing And Thawing Of Concrete Slideshare. When the water in concrete freezes it produces pressure in the pores of the concrete. Pavement damage due to freeze thaw cycles when the >91% of the pores of concrete are filled with water, the concrete is known to be saturated.

Freezing and thawing concrete damage is one of the more common diseases of concrete engineering in alpine regions, which is the damage caused by the physical action of concrete (dry and wet changes, temperature changes, freezing and thawing changes, etc.). The continuous freezing and thawing of water causes those tiny cracks to become larger over time. If the pressure developed exceeds the tensile strength of the concrete, the cavity will dilate and rupture.
