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?
Fast-setting concrete is ideal for setting posts because there's no mixing—you simply pour the dry concrete from the bag right into the hole, then add water.
Is there cement that will set in water?
Portland cement is a hydraulic cement that sets and hardens in the presence of water. Concrete made with Portland cement will harden even if it is completely under water.

Does concrete need to be kept wet?
ANSWER: Keeping concrete moist helps the curing process. Concrete hardens as a result of a chemical reaction, called hydration, between cement and water, not because it dries. If too much water is lost from the concrete through evaporation, the hardening process slows down or ceases.
When concrete is to be laid under water _ is to used?
Explanation: When concrete is to be laid under water, quick setting cement is to used.
Will a bag of quikrete set up underwater?
All hydraulic cements cure underwater, including Quikrete. Modern cement binders allow builders to pour concrete underwater and leave it to cure. As a result, pouring concrete underwater around a post is simple.
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.
