ABSTRACT
In order to investigate a cracking behaviour of concrete containing fly ash due to drying shrinkage, the restrained shrinkage cracking test of concrete specimens of ordinary Portland cement concrete and 20% fly ash concrete were performed. And drying shrinkage, creep, crack occurrence time, crack width and other characteristics were measured. Cracking tendency (crack occurrence time and crack width etc.) of fly ash concrete was almost the same as or a little superior to ordinary Portland cement concrete.
