Abstract

Plastic has become one of the most consumed materials in daily use worldwide, and its consumption is growing increasingly because of its low density, strength, low cost, formability and slow decomposition. However; the usage of plastic bottles is severe threat to environment in the form of plastic wastes. The rapid growth of PW is inviting attention for recycling and reusing in construction applications, which in turns to reduce the hazardous impact on environment. SCC is an influential innovation in concrete technology and overcome the application of normal concrete due to many attractive characteristics. Recently, the reinforcement of recycled plastic (RP) in SCC has increased due to many characteristics such as high workability, high liquidity and uniformity between the components of the mixture. Thus, this review work highlights the analyses of effect of RP fibres on SCC properties. On the basis of reviewed work in this paper, it can be concluded that the reinforcement of RP fibres could improve the fresh properties of SCC, whereas, in the hardened properties; the RP could enhance hardened properties of SCC to certain level but still lower than the steel reinforcement. However, RP reinforcement could advantageous to many environmental impacts to the SCC.

摘要

塑料已经成为全球日常使用中消耗最多的材料之一，并且由于其低密度，强度，低成本，可成型性和缓慢分解，其消耗量也在不断增长。然而; 塑料瓶的使用以塑料废物的形式严重危害环境。PW的快速增长引起了建筑应用中回收和再利用的注意，从而减少了对环境的有害影响。SCC是混凝土技术中的一项有影响力的创新，由于具有许多吸引人的特性而克服了普通混凝土的应用。最近，由于许多特性，例如高可加工性，高流动性和混合物各组分之间的均匀性，在SCC中增强了再生塑料（RP）的强度。从而，这篇综述着重分析了RP纤维对SCC性能的影响。根据本文的综述工作，可以得出结论，增强RP纤维可以改善SCC的新鲜性能，而在硬化性能方面则可以。RP可以使SCC的硬化性能提高到一定水平，但仍低于钢筋。但是，RP加固可能有利于SCC的许多环境影响。
