Water Curing Concrete Method

There are two methods to apply the water on concrete.

Water curing concrete method. Absorption of the heat of hydration promotion of hydration and elimination of shrinkage. This is by far the best method of curing as it satisfies all the requirements of curing namely promotion. Water curing is considered as the best method of curing of concrete as it satisfies all the requirements of curing namely. This is a widely used method of curing particularly for.

For example in building construction the curing of the floor slab can be done with this method. The application of the water is done to avoid the drying of the concrete surface. Ponding method is possible only on horizontal or flat surfaces of the structure i e. Sometimes concrete works are carried out in places where there is acute shortage of water.

The material used must be kept damp during the curing period. Water retaining methods use coverings such as sand canvas burlap or straw that are kept continuously wet. In the ponding method small rectangular or square artificial ponds are built with using bunds of. Water curing can be done in the following ways.

Immersion curing is usually done during concrete testing when curing concrete test specimens. Methods used for curing of concrete 1. Draining water on the concrete surface cures the concrete. Water cooler than 5 0 c is not suitable for curing concrete.

Usually this method applies when the concrete is thinner. Known as moist curing this. Procedure for curing of concrete. This is the most effective curing method for preventing mix water evaporation.

Used to cure flat surfaces on jobs or controlled areas where water can be easily retained on top of the. As the hydration reaction in concrete expels heat and keep concrete warm using cold water less than 5 0 c on concrete may lead to cracking and failing. Shading of concrete work. Water curing can be done using the following techniques.

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. In immersion method finished concrete is immersed in the. C spraying or fogging method. The object of shading concrete work is to prevent the evaporation of water from the surface.

Natural curing exposed concrete 1. Alternate drying and wetting on the concrete surface causes volumetric changes in concrete and ultimately leads to cracking. This is the best water curing method. Ponding method is one of the very well known and widely adopted methods in concrete curing.

Water curing method a immersion method.
