Which method of curing of concrete is recommendable for rapid gain of strength of concrete?

Method of  Curing

When to Use

Covering concrete surfaces with hessian or gunny bags

Adopted mainly in case of large concrete surfaces such as road slabs. 

Shading concrete work

Structural concrete work i.e. RCC work on beams/slabs

Pounding Method

Suitable for curing horizontal surfaces such as floors, roof slabs, road and air field pavements

Sprinkling of Water

Mostly used for curing floor slabs. 

Membrane curing

Adopted where water is not available in sufficient quantity or where constant supervision is not posible.

High-pressure steam curing

Adopted where strength development of concrete is very rapid.

Infrared radiation curing

It has much more rapid gain of strength can be obtained than even with steam curing.
