Chemical and Autogeneousshrinkage• During hydration of the cement paste in a closed system,the volume of the hydration products, , is less than the sumof the volume of water and the volume of cement that ishydrated. This leads to chemical shrinkage whosemagnitude can be expressed by(ε ch= V c+ V ) w− V hV ci+ V wiwhere and are the current and initial volume of cement, andand are the current and initial volume of water, respectively.
