<h2>The answer is:</h2>
Expansion and cracking
<h2>Explanation:</h2>
Whenever water freezes, it is expanded about 9 percent. Since the water in moist concrete freezes it producing pressure in the pores of the concrete. The collective effect of freeze-thaw cycles and disruption of aggregate can eventually cause expansion and cracking, scaling, and crumbling of the concrete that is formed from moist.
