Best answer

Concrete made with Portland cement will harden even if it is completely under water. In fact, one technique for curing a concrete slab is to build a soil dam around the perimeter of the slab, flood the slab with water and keep the slab covered with water for a week.

Can I mix cement with just water?

Asked By: Chris Ruehlemann Date created: Jun 22, 2022

Cement mixed with water alone creates a grout which can be used for repairing any damage on concrete structures. This cement-based grout mix is also used in situations where normal concrete won't work, such as underwater concreting. Concrete is used all over the world because it is durable, economical and versatile.

Asked By: mathematical.coffee Date created: Jun 11, 2022

Concrete needs time to cure before it can accept any finish coat of paint. For best results, allow a stamped concrete surface to cure for at least one year, preferably two years. As the concrete ages, the pores of the material exude moisture, minerals and trace amounts of salts.

Does concrete cure underground?

Civil engineer here. The concrete needs to stay wet in order to cure properly.
