As a review, the long-term autogenous shrinkage will first be described, since it is better understood and documented in practice. Long-term autogenous shrinkage in this paper refers to the deformations occurring after one day. The main material property controlling autogenous shrinkage is the w/c ratio: as the w/c ratio is lowered the autogenous shrinkage increases. This has
been explained by Powers and Brownyard [17] that autogenous shrinkage occurs due to self-desiccation when the w/c ratio is below about 0.42, since all mixing water is consumed at this ratio. This w/c limit can vary slightly, depending on the cement type and if there is an unrestricted supply of water available during curing.
