What Is The Freeze-Thaw Cycles Of Water In The Cracks Of Rocks. Once the crack has expanded, and the ice has melted, more water can fill up the gap in the rock. If the pressure developed exceeds the tensile strength of the concrete, the cavity will dilate and rupture.
The cracks formed in soil by freezing and expansion of water can occur on a tiny scale. What happens when we get a little closer? Since the crack is bigger, it can hold more water this time around.
