| Abstract: | This article focus on the first phase of the project of Anhui Province New Broadcasting Center. The CT-1,the thickness of shape of the main cylinder based caps is 3.5 m, which belongs to the Massive concrete structure. In order to overcome the crack caused by exorbitant of the hydration heat in massive concrete, the project take several measures including Optimize dosage of cement concrete mixture, setting post- cast strip, cant layered casting, after implementing concrete pouring temperature monitoring, and so on. All these measures restrain temperature and concrete crack successfully, guarantee the construction quality of massive concrete foundation caps. |
| Keywords: | massive concrete foundation caps temperature control crack control |
