Rebar rusting: When rebar rusts it can expand up to 4 times its diameter which puts tremendous pressure on the concrete. This pressure causes the concrete to crack and at ...
Causes of Spalling. Moisture and freezing: Porous and cracked concrete allows moisture to penetrate and when the water freezes, it expands approximately 9% in volume; this then causes additional cracks and spalling.
