Abstract

This experimental investigates presents the use of three types of plastic wastes as fine aggregates in concrete as an effective way to deal with the scarcity of natural aggregate and problems related to disposal of plastic. This work emphasises on using plastic waste from different source such as water drink bottle, compact disk, and plastic cover of water drink bottle to substitute fine aggregate partially. This research investigates the performance of concrete subjected to compression and impact loading besides to bond strength for the following plastic percentages: 0% (reference), 10%, 15%, 20% and 25% as partial substitution. The results show that fine plastic aggregate reduce compressive strength and modulus of elasticity of concrete and the specimens were suffered from more deformations before failure under compression and impact loads comparing with control specimen. In addition, the bonding strength between concrete and steel reinforcement decreased with increasing of plastic content especially the one with bigger particle size one.

以废塑料为细骨料的混凝土承受压缩、冲击载荷和抗粘结性能

摘要

本实验研究提出了在混凝土中使用三种塑料废料作为细骨料,作为解决天然骨料稀缺和塑料处置相关问题的有效方法。这项工作强调使用来自不同来源的塑料废物,如水瓶、光盘和水瓶的塑料盖来部分替代细骨料。本研究调查了混凝土承受压缩和冲击载荷的性能以及以下塑性百分比的粘合强度:0%(参考)、10%、15%、20% 和 25% 作为部分替代。结果表明,与对照试件相比,细骨料降低了混凝土的抗压强度和弹性模量,试件在压缩和冲击荷载作用下发生更多的破坏前变形。此外,混凝土与钢筋之间的结合强度随着塑料含量的增加而降低,尤其是粒径较大的一种。
