Water Curing Concrete Time

One of the most common methods for curing concrete is to hose it down frequently with water five to 10 times per day or as often as you can for the first seven days.

Water curing concrete time. 75 of compressive strength achieved in 14 days. During this process the ingredients in the concrete bind together and form the eventual concrete structure. Normally curing of ordinary portland cement concrete may take a minimum of 7 days after placement. During this process moisture in the mix escapes to the top often over the course of about 28 days.

Concrete which is moist cured for 7 daysis about 50 stronger than uncured concrete. Curing concrete with water prevents excessive loss of moisture as the water will create a layer for an extended period of time that can control the evaporation of moisture from the surface. Water curing can be done after the slab pour by building dams with soil around the house and flooding the slab. For a clear understanding check the below graph.

If you do curing of concrete for a longer time there are more chances of a better strength of the structure and vice versa. 90 of concrete design strength achieved in 28 days. Known as moist curing this. After some time the concrete will start the chemical reaction that will eventually harden the concrete.

Traditional way to cure concrete. On average curing for 7 to 14 days gives better results in terms of achieving the objectives. The minimum period for curing concrete to attain maximum strength is 28 days.
