Steel-polyethylene hybrid fiber doped recycled aggregate concrete and preparation method thereof
The invention discloses recycled aggregate concrete doped with steel-polyethylene hybrid fibers and a preparation method of the recycled aggregate concrete. The recycled aggregate concrete doped with the steel-polyethylene hybrid fibers is prepared from the following raw materials: cement, natural coarse aggregate, natural fine aggregate, recycled coarse aggregate, water, steel fibers and polyethylene fibers, wherein the mass ratio of the cement to the natural coarse aggregate to the natural fine aggregate to the recycled coarse aggregate to the water to the steel fibers to the polyethylene fibers is 1 to (1.44 to 1.51) to (1.69 to 1.77) to (1.44 to 1.51) to (0.52 to 0.57) to (0.060 to 0.14) to (0.002 to 0.007). The steel fibers and the polyethylene hybrid fibers are doped into the recycled concrete, so that the defects of the recycled concrete in the aspects of compressive strength, splitting tensile strength, ductility, crack resistance and the like can be overcome, and the mechanical property of the recycled concrete can be effectively improved; and the requirements of green building materials are met, and good social benefits, environmental protection benefits and economic benefits are achieved.
本发明公开了一种掺入钢‑聚乙烯混杂纤维的再生骨料混凝土及其制备方法。该掺入钢‑聚乙烯混杂纤维的再生骨料混凝土的原料包括：水泥、天然粗骨料、天然细骨料、再生粗骨料、水、钢纤维、聚乙烯纤维，且水泥、天然粗骨料、天然细骨料、再生粗骨料、水、钢纤维、聚乙烯纤维的质量比为1:(1.44～1.51)：(1.69～1.77)：(1.44～1.51)：(0.52～0.57)：(0.060～0.14)：(0.002～0.007)。本发明通过向再生混凝土中掺入钢纤维和聚乙烯混杂纤维，可以弥补再生混凝在抗压强度、劈裂抗拉强度、延伸率和抗裂性等方面性能的不足，能够有效改善再生混凝土的力学性能，符合绿色建筑材料的要求且具有良好社会效益、环保效益和经济效益。
