摘要
实现“碳达峰、碳中和”是国家作出的重大战略,为了评价再生混凝土建设过程的碳排放,文章基于生命周期分析方法建立再生混凝土当量碳排放评价体系,分析了原材料生产、原材料运输、混凝土生产以及混凝土运输四个阶段的碳排放总量,并探讨了再生骨料掺量以及运输距离对该过程碳排放总量的影响。
"Carbon peak and carbon neutrality"is a significant national strategy.To assess carbon emissions in the construction process of recycled concrete,this study develops an evaluation system for equivalent carbon emissions based on the life cycle analysis approach.It examines the total carbon emissions across four stages:raw material production,raw material transportation,concrete production,and concrete transportation.Furthermore,the study investigates the impact of recycled aggregate content and transportation distance on the overall carbon emissions during the process.This research contributes to the field of civil engineering and green building materials by providing insights into the life cycle and carbon emissions of recycled concrete.
