工业废料混凝土能值原始数据.docx

本研究提出了一种将能值理论与生命周期评估（LCA）相结合来评估工业固体废物混凝土可持续性的新方法。它考虑mergy 转化率和污染排放因子，以考虑m混凝土生命周期四个关键阶段的 e m ergy 投入和污染排放数据。通过mem ergy和污染物的动态流动m说明了常规混凝土和三种不同类型的工业固体废物混凝土的 研究结果表明，生产阶段对m各种混凝土类型的贡献占90%以上的能源投入和污染排放，其中含有工业废料的混凝土消耗更多，m预处理和运输过程中产生更多的排放。在维护和废物处理阶段，各种混凝土类型表现出相对相似的能量m输入和污染排放水平。按单位体积计算，m三种工业废料混凝土类型与传统混凝土的总投入量差异分别为+0.17%、-1.05%和0.84%，表明某些空气污染物（如二氧化碳排放量）减少了22.9%、58.28%和33.1%。本研究最终为未来的固体废物管理和减排政策提供了重要的理论支持。

This study proposes a novel method that combines emergy theory and Life Cycle Assessment (LCA) to evaluate the sustainability of concrete produced using industrial solid wastes. It considers emergy conversion rates and pollution emission factors to account for emergy inputs and pollution emission data across the four key stages of the concrete life cycle. By analyzing the dynamic flows of emergy and pollutants for conventional concrete and three types of industrial solid waste-incorporated concrete, the research findings indicate that the production stage accounts for over 90% of the energy inputs and pollution emissions across all concrete types. Concrete incorporated with industrial solid wastes consumes more energy and generates higher emissions during the pretreatment and transportation processes. During the maintenance and waste disposal stages, all concrete types exhibit relatively similar levels of energy inputs and pollution emissions. Calculated per unit volume, the total input differences between the three industrial solid waste-incorporated concrete types and conventional concrete are +0.17%, -1.05%, and 0.84% respectively, indicating that certain air pollutants (e.g., carbon dioxide emissions) are reduced by 22.9%, 58.28%, and 33.1% correspondingly. This study ultimately provides important theoretical support for future solid waste management and emission reduction policies.
