Never pour concrete into a hole if there is standing water in it. Excess water increases the water-to-cement ratio in the concrete mix, which also reduces the strength of the concrete.
Thereof, Should I put water on concrete after it is poured?
Spraying water on your new concrete is one of the best and oldest ways to cure your concrete. After new concrete is poured and finished the concrete begins its curing process. … Spraying water on the surface prevents the surface of the concrete slab from drying faster than the bottom.

Subsequently, question is, How long does it take for cement to cure under water? 3-7 days
Also, How long does concrete take to cure under water?
3-7 days
Does concrete go off under water?
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.
How long will concrete last underwater?
Quikrete requires three days to cure underwater. If you simply put the bags around the post and allow the water to saturate the cement, leave the legs up for one week to ensure that the concrete sets.
How does underwater concrete work?
Under The Water The type of cement used for most construction, including underwater construction, is Portland cement. … In fact, cement sets by reacting chemically with water. Most of the water in the mixture is used up not by evaporation, but by reacting with compounds in the cement to produce very hard, new compounds.
Does cement harden under water?
Will concrete harden under water? Portland cement is a hydraulic cement which means that it sets and hardens due to a chemical reaction with water. Consequently, it will harden under water.
Does water affect concrete?
Water is an essential component when making concrete. The moisture that water provides also gives concrete its strength during the curing process. While water is one of the most important ingredients in concrete, it can also be the most destructive in excessive amounts.
What do you spray on concrete after pouring it?
Sealants, much like those used to protect wooden decks, are applied to protect the finished and cured concrete surface. … Membrane curing works by adding a liquid compound called a cure and seal. You can spray or roll this onto the surface of your concrete as soon as your finish is complete.
How soon after pouring concrete should you wet it?

What is the fastest way to cure concrete?
Plastic Tarps Cover the concrete with a plastic sheet to trap moisture escaping from the concrete. This moisture helps concrete to cure faster without drying out too quickly.
What kind of cement is used underwater?
