摘要
从混凝土用水量、原材料选择入手,采取多种防裂措施进行抗裂混凝土配合比设计。根据混凝土变形性能和热学性能的研究结果,确定混凝土补偿收缩的限制膨胀率。云峰大坝应用结果表明,防裂混凝土具有较好的抗裂性。
Starting with the water consumption and material selection of concrete,the paper takes many anti-crack measures to design the mix proportion,ensures the limited expansion rate of shrinkage-compensating concrete based on the results of the deformation and thermal property of concrete.The application result in Yunfeng dam shows the anti-crack concrete has a better crack resistance.
