Drying Shrinkage of Cement
and Concrete:
Reducing concrete drying Shrinkage Some of the measures that can be taken to reduce the drying shrinkage of concrete include: n Use the minimum water content (consistent with placing and finishing requirements). n Use highest possible volume fraction of good quality aggregate and maximum possible aggregate size. n Use Shrinkage Limited Cement (Type SL) where available. n Do not use admixtures known to increase drying shrinkage, eg those containing calcium chloride. n Ensure concrete is properly placed, compacted and cured.
