摘要
为了研究纤维对海水海砂混凝土基本力学性能的影响效果,通过设定玻璃纤维和聚丙烯纤维在体积掺量为0.1%、0.2%、0.3%,以及两者混掺体积分数为0.3%前提下的混杂比为1∶2、1∶1、2∶1,分析混凝土试块的抗压强度、劈裂抗拉强度、静弹性模量三者的变化规律。结果表明:掺入适量的纤维可以在一定程度改善海水海砂混凝土的基本力学性能,可为实际海洋工程建设提供参考。
In order to study the effect of fiber on the basic mechanical properties of seawater sand concrete,the mixing ratio of glass fiber and polypropylene fiber is set as 1∶2,1∶1,2∶1 under the premise that the volume content of glass fiber and polypropylene fiber is 0.1%,0.2%,0.3%,and the volume fraction of their mixing is 0.3%,the changing rules of compressive strength,splitting tensile strength and static elastic modulus of concrete test block are analyzed.The results show that adding appropriate amount of fiber can improve the basic mechanical properties of seawater sand concrete to a certain extent,which provides a certain reference value for the actual construction of ocean engineering.
