摘要:
结合杨家岭溢洪道闸墩实际工程,对以温度控制指标为主的闸墩混凝土相关力学性能进行了试验研究.试验结果表明,掺入适量的聚丙烯纤维(0.9 kg/m3)可较明显地提高闸墩混凝土的抗裂性能;对于缺乏试验资料的水利工程,可根据28 d龄期混凝土抗压弹性模量计算混凝土其它龄期的抗压弹性模量,也可根据混凝土的立方体抗压强度计算混凝土的抗压弹性模量.
Abstract:
Combined with the actual project of Yangjialing spillway gate pier, the relevant mechanical properties of gate pier concrete based on temperature control index were experimentally studied. The test results show that the addition of an appropriate amount of polypropylene fiber (0.9 kg/m3) can significantly improve the crack resistance of the gate pier concrete. For hydraulic projects lacking test data, the compressive elastic modulus of concrete of other ages can be calculated according to the compressive elastic modulus of 28 d age concrete, and the compressive elastic modulus of concrete can also be calculated according to the cubic compressive strength of concrete.
