Abstract

The scope of this study is to review recent publications in the area of the concrete manufacturing industry to study its the environmental impacts from a Life Cycle Assessment (LCA) perspective. This study also integrates LCA in recent publications, greenhouse gas emission, ozone layer, nutritionist, photochemical oxidation, impact on terrestrial ecotoxicity, and human toxicity on building material waste recycling. It also classifies different product stages and reviews different methodologies, assumptions, and limitations. The results show the effects of applying recycled aggregates and supplementary cementitious materials (SCMs) on the mechanical and durability properties of concrete have not been addressed well in the previous research works. In furtherance of this study, the significance of concrete mixes compared in the same range of compressive strength (CS) and equal service life, as well as the necessity of sensitivity analysis, have been discussed.

摘要

本研究的范围是回顾混凝土制造业领域的最新出版物，以从生命周期评估 (LCA) 的角度研究其对环境的影响。该研究还整合了近期出版物中的 LCA、温室气体排放、臭氧层、营养学家、光化学氧化、对陆地生态毒性的影响以及对建筑材料废物回收的人类毒性。它还对不同的产品阶段进行了分类，并审查了不同的方法、假设和限制。结果表明，在以前的研究工作中，应用再生骨料和补充胶凝材料 (SCM) 对混凝土的机械和耐久性能的影响并未得到很好的解决。为了推进这项研究，
