摘要
混凝土作为一种广泛使用的建筑材料，尽管在建筑项目中具有很强的适应性，但也存在各种局限性。它在受到拉力时表现出软弱无力，延展性受到限制，抗裂性极差。混凝土因其强度高而被广泛应用于建筑领域。本研究的目的是对 PET 纤维作为建筑材料在混凝土中的应用进行实验研究，这种材料既符合技术要求，又对环境无害。在各种工程应用中使用 PET 纤维可以解决塑料垃圾的处理问题。在混凝土中使用 PET 纤维可以改善混凝土的延性参数。本研究使用了长度为 50 毫米、宽度为 3 毫米的 PET 纤维丝。对 M30 级混凝土进行的测试包括评估其压缩强度、劈裂拉伸强度、弯曲强度和抗冲击性。纤维的添加比例分别为 0%、0.25% 和 0.5%。研究了 PET 纤维混凝土的冲击性能。试验结果表明，添加 PET 纤维后，混凝土的抗压强度、劈裂拉伸强度和抗折强度都有所提高，抗冲击性也显著增强。
Experimental Investigation of Effect of Waste PET fibres on the Impact Behaviour of PET Fibre Reinforced Concrete
Concrete, being the construction material that is extensively employed, possesses various limitations despite its adaptability in building projects. It exhibits weakness when subjected to tension, has restricted ductility, and offers minimal resistance against cracking. Concrete is widely used in construction due to its high strength. The aim of this study is to conduct experimental research on the utilization of PET fibre as a construction material in concrete, which is technically sound and environmentally safe. The use of PET fibre in various engineering applications can solve the problem of disposal of plastic waste. PET fibre can be used in concrete to improve its ductile parameters. PET wires of 50 mm in length and 3 mm in width are used in this work. The tests conducted on M30 grade concrete included assessments of its strength in compression, strength in split tensile, strength in flexure, and resistance to impact. The percentages of addition were 0 %, 0.25 % and 0.5 % density of fibre. The impact properties of PET fibre concrete were studied. Test results showed that there is improvement in compressive strength, split tensile strength, flexural strength and a significant increase in impact resistance of concrete after the addition of PET fibres.
