What Happens When You Put Concrete In Water?

What happens when you put concrete in water? When a concrete mixture is too wet, it causes a greater amount of shrinkage during the drying process than is needed. As a result, the concrete has a great likelihood of cracking and for those cracks are likely to be a fairly good size. A watery mix actively reduces the compressive strength of the dried concrete.

Does submerging concrete in water make it stronger?

DO spray new concrete with water.

Moist-cured concrete can be up to 50 percent stronger than concrete that was cured without being dampened!

Can you pour concrete in hole then water?

How much water do I add to quick set concrete?

Pour water into the dry mix until the powder is saturated with water. Depending on soil conditions, this will require about 1 gallon (3.8 L) of water per 50 lb (22.7 kg) bag. For holes deeper than 2' 6" (0.8 m), place the material in lifts of 2' 6" (0.8 m) or less to allow water to soak all the way through.
