Abstract

The growth of post consumed plastic wastes requires recycling to save the environment against pollution. One solution is the reuse of the waste as a substantially material for concrete production. Different properties of concrete containing different plastic wastes have been investigated by the past researchers. In this study, impact strength and behavior of normal strength concrete contained shredded PVC waste aggregate or PET waste fiber has been investigated experimentally. Results show that there is a first crack impact and ultimate impact loads enhancement of 97% and 23% as a result of using 20 mm length PET fiber added to concrete by 0.75%. The impact performance of 40 mm length PET fiber was found to be lower as compared with that of 20 mm length fiber to enhance impact. There is a reduction in both first crack impact and ultimate load impact of concrete as a result of replacing a part of fine aggregate with a PVC waste aggregate reaching 84% related to using 45% PVC aggregate as fine aggregate replacement. Results also show that there is a strong linear relationship between the first crack impact and ultimate load impact for concrete contained PET fiber or PVC aggregate.

含不同塑料废料混凝土的冲击强度和性能

消费后的塑料废物的增长需要回收，以保护环境免受污染。一种解决方案是将废物作为混凝土生产的主要材料进行再利用。前人研究了不同塑料废弃物对混凝土性能的影响。试验研究了含碎PVC废骨料和PET废纤维的普通强度混凝土的冲击强度和性能。结果表明:20mm长度PET纤维掺量为0.75%时，混凝土的初裂冲击和极限冲击载荷分别提高97%和23%;40mm长PET纤维的抗冲击性能比20mm长PET纤维的抗冲击性能要低。用PVC废骨料替代部分细骨料达到84%，与用45% PVC骨料替代细骨料有关，降低了混凝土的初裂冲击和极限荷载冲击。结果还表明，含PET纤维或PVC骨料混凝土的首次裂缝冲击与极限荷载冲击之间存在较强的线性关系。
