Crack Control Technology of Massive Concrete with Thick Foundation Floor
In the first phase of the project of AnHui Province New Broadcasting Center, the CT-1 foundation of tube cushion cap in main building is 3.5m in thickness which belongs to massive concrete. In order to prevent the crack caused by the excessive hydration heat in massive concrete, the project take several actions including optimizing dosage of cement concrete mixture, setting post-cast strip, cant layered casting and temperature monitoring after concreting, etc. All these actions regulate the concrete temperature and restrain crack generation successfully, while insuring the construction quality of massive concrete cushion cap.
