Will a bag of concrete harden under water?
Yes, concrete doesn’t ‘ dry’ when it sets, it completes a chemical reaction. Any drying weakens the reaction so concrete that sets underwater can be stronger than concrete that sets in air. The trick when pouring underwater is to ensure the concrete is fed to the final position without ‘falling’ through the water.Click to see…

Considering this, can you pour concrete in standing water?The good news is that you can pour the concrete in water. The biggest issue with pouring concrete under water is movement. If the water is moving, it can wash away the cement paste that’s holding the sand and gravel together. But if the water is calm, then it’s not a problem at all.One may also ask, which cement is used in underwater construction? Portland cement Also asked, how long does it take for concrete to set under water? Allow the concrete to cure before removing the 2-by-4-inch legs. 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.Does concrete dissolve in water?The amount of water placed in the initial concrete mix has a great deal to do with its strength. Concrete in and of itself does not dissolve in rain, but cement does and since cement is the “glue” that holds everything together, concrete becomes useless when inundated with rain.
