Methods of Curing of Concrete

Methods of Curing of Concrete

” The process of application of water over the surface to support hydration is called curing.”

Curing may be carried out over the plastered surface or concrete surface.

It is done to keep the surface damp that provides required water to the cement for the chemical reaction to make concrete hard and strong.

The strength of concrete increases more rapidly in initial stages but after a few days; strength of concrete increases slowly. Generally, 14 days of curing work are required for concreting work.

Curing is not only the application of water over the concrete /  plastered surface; preventing the loss of moisture is also the type of curing. Two different ways of curing are: 


1. Application of water to the surface
E.g. Spraying, ponding, immersion, damp sand, etc.


2. Preventing the loss of moisture
E.g. Continuous wetting the surface, using different compounds, etc.



Methods of curing of concrete

Different methods of curing are:



-Water is sprayed to the concrete surface by the use of different spraying tools and pipes.

-It is suitable for curing vertical surface of concrete-like walls, pillars, etc.

2. Wet Curing

-The main aim of wet curing is to prevent moisture loss from the surface.

– Wet curing is done by the use of jute bag, wet sand, etc. 

– This method is suitable for a hot climate.



3. Ponding

–  In this method, small ponds are made and water is filled on it. 

– It is best for horizontal curing of concrete.



4. Immersion

– To immerse the concrete of small-size into a water tank; this method is used.

– It is best for separate small concrete elements like the cover of the tank ( concrete cover).



Result of lack of curing 

Lack of curing leads to the following:

1. Cracks of concrete and plasters.

2. When the paint is applied to the surface which is not cured properly, it leads to non-uniformness, non-smoothness and aligatering of paint. 

3. Efficiency is decreased by nearly 50 %.
