建筑垃圾再生砖的力学性能与环境影响评价

Mechanical Properties and Lifecycle Assessment of Recycled Bricks Made of Construction Waste

在拆迁后的建筑垃圾中,回收废弃混凝土和黏土砖,将其加工为再生骨料,重新制成建筑用砖.通过实验,确定了该再生砖符合相关规范.通过测定该再生砖块的各项技术指标、经济成本分析和环境影响评价,并与普通黏土烧结砖进行对比.结果表明,该再生砖在力学、热学性能方面的优越性,具有环境友好型以及生产与社会效益.

By recycling waste concrete and bricks from the construction waste,they are processed into recycled aggregate to make the construction bricks.Through experimental inquiry,this paper finds the recycled bricks to meet the national norms.By measuring the technical indicators,economic cost analysis and environmental impact assessment,compared with ordinary clay fired bricks,the technical recycled bricks show the superiority in mechanical and thermal performance,environmental friendliness,and social and environmental benefits of production.
