Reducing drying shrinkage of concrete by treatment of aggregate [PDF]

, 2010
Drying shrinkage of concrete has been found to cause cracking, water leakage and other serviceability problems and is thus an important research topic. In early studies, it has been found that the shrinkage of concrete varies with the rock aggregate used.
