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.
Curling of a slab soon. after placement is most likely related to poor curing. and rapid surface drying. In slabs, excessive bleeding. due to high water content in the concrete or water. sprayed on the surface; or a lack of surface moisture. due to poor or inadequate curing can create increased. surface drying shrinkage relative to the bottom of the. slab.
