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.
See CIPs 13 and 20 for discussions on. blisters and delaminations, respectively. Due to the inherent higher total moisture content of. lightweight concrete it typically takes a longer time than. normalweight concrete to dry to levels that might be. considered adequate for application of floor covering. materials.
