The drying shrinkage of concrete is analogous to the mechanism of drying of timber specimen. The loss of free water contained in hardened concrete, does not result in any appreciable dimension change. It is the loss of water held in gel pores that causes the change in the volume.
Curing serves two main purposes. 1  It retains moisture in the slab so that the concrete continues to gain strength. 2  It delays drying shrinkage until the concrete is strong enough to resist shrinkage cracking.
