| Abstract: | Based on characteristics of mass concrete,cracking causes of mass concrete are analyzed including high hydration temperature rising,tension stress in concrete and low tension strength of concrete.Then,anti-cracking measures are suggested,such as reducing temperature rising by reasonably choosing materials and construction methods,eliminating or reducing restriction,as well as rising concrete tension strength. |
