| Abstract: | The footing of Xilin Bridge (cable-stayed) in the Project of Changzhou Viaduct (I) is built by massive concreting. To prevent the mass concrete from cracking, measures are taken in five aspects, such as selection and adaption of materials, grouting temperature, burial and control of the cooling coil, control over difference in the internal and external temperatures, formwork removal and cure of concrete, with the proposal for temperature control. From the temperature record monitored, the control results are shown. |
