I guess its because water is evaporated and the concrete becomes compact.

What is the process of that ordinary cement concrete will shrinks after casting on drying?

@Bhagyashree.
It is not so that the water will evaporate and concrete will get compact.
Only thing is that the chemical process will going on inside the concrete structure thats why it get shrinks.
Curing is done to protect the inside chemical action against evaporate to get strengthen the structure.
If the curing is not done within the time then the structure will definitely cracks, and may chance to collapse.

It shrink because of capillary pressure.

Concrete shrinks after drying due to loss of water by evaporation which results in shrinkage cracks.
Proper curing is hence required to contain the shrinkage cracks.

Drying shrinkage is defined as the contracting of a hardened concrete mixture due to the loss of capillary water. This shrinkage causes an increase in tensile stress, which may lead to cracking, internal warping, and external deflection, before the concrete is subjected to any kind of loading.

On drying there is a decrease in volume of the concrete.

Concrete shrinks after casting due to the chemical reaction known as HEAT OF HYDRATION, due to this action the water present in concrete will evaporate as per the required period. Finally the loss of water in concrete cause shrinkage in concrete.

Concrete shrinks after drying due to the voids are filled by air after drying. It is considerably filled by water. Water will evaporate from that place by drying. . Thus it shrinks.

Give me the answer if Shrinkage in concrete is increased.
