Top best answers to the question «Will concrete set underwater»

Concrete made with Portland cement will harden even if it is completely under water. In fact, one technique for curing a concrete slab is to build a soil dam around the perimeter of the slab, flood the slab with water and keep the slab covered with water for a week.

Concrete can dry underwater even much better than it does in air. This happens when cement particles hydrate. The cement reacts chemically with water, binding together the sand and gravel. This curing (hardening) process takes almost a month and causes the concrete to set.
