Shrinkage. Definition: decrease in either length or volume of a material resulting from changes in moisture content or chemical changes.- ACI Concrete Terminology. Drying shrinkage is the contraction in the concrete caused by moisture loss from drying concrete. Shrinkage-compensating concrete is used to minimize cracking and structural movement caused by drying shrinkage in concrete. The amount of drying shrinkage that occurs in concrete structures depends on the constituent materials, mixture proportions, curing, drying environment, and restraint.
Figure 3-1: Fly ash improves workability for pavement concrete. Decreased water demand. The replacement of cement by fly ash reduces the water demand for a given slump. When fly ash is used at about 20 percent of the total cementitious, water demand is reduced by approximately 10 percent.Higher fly ash contents will yield higher water reductions. The decreased water demand has little or no effect on drying shrinkage/cracking.hen fly ash is used at about 20 percent of the total cementitious, water demand is reduced by approximately 10 percent.
