The influence of fly ash with different additions on the early shrinkage and cracking of cement-based materials were investigated by means of the shrinkage tests and initial cracking time.Moreover,the relation between cracking and shrinkage cracking of cement-based material with fly ash were studied.Results showed that shrinkage of cement-based materials is decreased due to the effect of fly ash,also to a certain extent,fly ash could prevent from cracking due to early-age cracking.
