摘要
通过改变混杂钢纤维掺率,试验分析了其对再生骨料混凝土基本力学性能及梁抗裂性能的影响,结果表明,混杂钢纤维的掺入可以有效提高混凝土的抗压强度与劈拉强度,延迟混凝土梁开裂,阻碍裂缝发展,并减小梁在屈服时的最大挠度。
In this paper,by changing the hybrid steel fiber ratio,to study its effect on the basic mechanical properties and crack resistance of recycled aggregate concrete beams. The results show that the hybrid steel fiber can improve compressive strength and splitting tensile strength of concrete,effectively delayed cracking of concrete beams,hinder the crack development and reduce the maximum deflection.
