Abstract

Nowadays, sustainable construction materials are becoming popular in the construction industry. The path towards sustainability development indicates minimisation of environmental impacts of the construction industry. In the view of this, increased environmental and financial concerns related to dumping construction and demolished waste (C&DW), using recycled concrete aggregates (RCA) as a replacement (partial or full) of natural aggregates (NAs) are getting appreciable attention in the construction industry. This review article comprehensively discusses the production, properties and enhancement methods of RCA. This article also documents the microstructure and properties of recycled aggregate concrete (RAC) and methods to improve its performance.

摘要

如今，可持续建筑材料在建筑行业中越来越受欢迎。通往可持续发展的道路表明建筑业对环境的影响最小化。有鉴于此，与倾倒建筑和拆除废物 (C&DW) 相关的环境和财务问题日益增加，使用再生混凝土骨料 (RCA) 作为天然骨料 (NAs) 的替代品（部分或全部）在施工中受到了相当大的关注行业。这篇综述文章全面讨论了RCA的产生、性质和增强方法。本文还记录了再生骨料混凝土 (RAC) 的微观结构和性能以及提高其性能的方法。
