摘　　要：针对橡胶纤维增韧混凝土的可行性,为橡胶纤维的工程应用提供参考,将纤维状橡胶按体积等比例取代砂石掺入混凝土中,研究了混凝土的坍落度、含气量、混凝土抗压强度、和弯拉强度以及变形能力的变化。试验结果表明,橡胶粒对混凝土含气量影响很大,明显影响强度,对降低混凝土脆性也不利,需加以控制;橡胶纤维对抗压强度影响大于橡胶粒,抗折强度两者相当;同时掺橡胶纤维的混凝土在承受弯拉荷载至破坏的过程中,有良好的变形特性,体现了橡胶纤维良好的增韧效果。The differences of slump,, air content, strength and deformation performance were studied by making concrete using rubber, fiber in place of aggregate. Studies show that air content obviously affects the strength and it＇s disadvantageous to reducing brittleness, rubber fiber affects the compressive strength more than rubber particles and when concrete are bended, the concrete with rubber fiber has better deformation performance.
