摘要:
为改善再生混凝土脆性大、易开裂的缺陷,掺入3种不同体积分数(0.1%,0.2%,0.3%)的聚乙烯纤维得到纤维增强再生混凝土,开展了坍落度、立方体抗压强度和劈裂抗拉强度试验。结果表明:掺入体积分数为0.2%的聚乙烯纤维时,再生混凝土的立方体抗压强度提升幅度最大(10.3%)。纤维的掺入降低了再生混凝土的坍落度,当聚乙烯纤维体积分数为0.3%时,坍落度降低幅度最大(18.2%)。再生混凝土的劈裂抗拉强度和拉压比随纤维体积分数的增加而提高,聚乙烯纤维体积分数为0.3%时,劈裂抗拉强度和拉压比分别提高了22.5%、16.9%,纤维的掺入改善了再生混凝土的脆性。
Abstract:
To improve the defects of recycled concrete which is brittle and prone to cracking, the fiber-reinforced recycled concrete was obtained by mixing three different volume fractions(0.1%, 0.2%, 0.3%) of polyethylene fibers. Their slump, cubic compressive and splitting tensile were investigated. The results show that the cubic compressive strength of the recycled concrete increases by a maximum of 10.3% when polyethylene fibers with a volume fraction of 0.2% are incorporated. The incorporation of fibers reduces the slump of the recycled concrete, and the maximum slump reduction is 18.2% when the polyethylene fiber volume fraction is 0.3%. The splitting tensile strength and the tensile to compressive ratio of recycled concrete increase with the increase of fiber volume fraction, and they increase by 22.5% and 16.9% respectively when the volume fraction of polyethylene fiber is 0.3%, demonstrating the incorporation of fiber improves the brittleness of recycled concrete.
