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.
3(a). Bleeding in concrete is sometimes referred as water gain. It is a particular form of segregation, in which some of the water from the concrete comes out to the surface of the concrete, being of the lowest specific gravity among all the ingredients of concrete.Bleeding is predominantly observed in a highly wet mix, badly proportioned and insufficiently mixed concrete.arly bleeding when the concrete mass is fully plastic, may not cause much harm, because concrete being in a fully plastic condition at that stage, will get subsided and compacted. It is the delayed bleeding, when the concrete has lost its plasticity, which causes undue harm to the concrete.
