| Abstract: | Some methods such as adding ice into concrete and enhancing tensile performance itself are adopted in the construction of bottoms-plates with mass concrete in Shenzhen Convention and Exhibition Center, which can effectively control the cracks occurring in the mass concrete. In the construction of the extra-long wall concrete in the basement, because of adopting several measures such as reducing the water-ash proportion, adding the special fiber, and prolonging the form removal time, the crack occurrence, which is caused by external shear force walls, can be avoided basically. |
