Top best answers to the question «How does concrete set underwater»

  • How Does Concrete Set Underwater? When concrete is poured underwater, one of its compounds reacts with water to form an outer coating. This coating prevents a lot of water from either seeping in or worse, diluting the cement. Next, another compound in the concrete reacts at a slower pace and sets to its final hardness 28 days later.

How Does Concrete Set Underwater? When concrete is poured underwater, one of its compounds reacts with water to form an outer coating. This coating prevents a lot of water from either seeping in or worse, diluting the cement.

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.
