Abstract: Cracking is a familiar problem in concrete engineering and is thought to be a serious factor contributing to the deterioration in the durability and appearance of concrete structures. For decades expansive agents for concrete have been developed and employed to solve this problem. However, practice has proven that cracking could not always be effectively avoided, especially for mass concrete structures. This research tried to investigate the causations of failure of the expansive concrete to overcome thermal cracking, mainly based on the experimental and analytical results of volume changes and restrained stress. In addition, it was confirmed that concrete mixed with lightweight aggregate can effectively eliminate the effect of autogenous shrinkage.
