摘　　要：通过试验研究了部分钢纤维橡胶高强混凝土的力学性能,探讨了钢纤维掺量对其基本力学性能的影响。结果表明:部分钢纤维橡胶高强混凝土的抗压强度、劈裂抗拉强度和抗折强度均随钢纤维体积率的增大而增大,钢纤维和橡胶粉的加入改善了高强混凝土的脆性破坏特性。采用部分掺入钢纤维是一种降低钢纤维橡胶高强混凝土成本的有效措施。The properties of partial steel fiber modified high strength recycled rubber concrete are tested and analyzed,including the influence of the fraction of steel fiber volume.Test results show that the compressive strength,splitting strength and flexural strength were improved as the increase of the fraction of steel fiber volume.The addition of steel fiber and recycled rubber powder improved the ductility of high strength concrete.It is an effective measure to reduce costs for steel fiber modified high strength recycled rubber concrete by adding partial steel fiber.
