Dry shrinkage of concrete is occurred due to the cement hydration and water evaporation from early ages, and it induces crack of concrete. In this study, shrinkage according to sand-aggregate and water-binder ratio were compared with the existing prediction models. From the results, when sand-aggregate ratio and unit water content increase, dry shrinkage of concrete increase. But, it showed that existing prediction models do not reflect shrinkage of concrete, well.
