【摘要】 简述了产品生命周期评价和资源耗竭影响,在综合资源储量、年消耗量和回收率的基础上提出了资源耗竭影响和当量系数的计算方法。通过分析几种不同强度等级的掺与不掺粉煤灰混凝土的实验,定量评价了混凝土物化能耗及资源耗竭指数。研究结果有助于绿色建筑设计合理选择混凝土强度等级和加强混凝土生产的资源科学管理。更多还原

【Abstract】 The products of life cycle assessment(LCA) and resources consumption impact(RCI) are reviewed briefly.Based on the comprehensiveness of the reserves,annual consumption and recovery rate,a method calculating RCI and their equivalency factors is proposed.Through experimental analysising several different strength grades of concrete and fly ash concrete,the embodied energy and resources consumption indicator is quantitatively assessed.The result is helpful to choice the reasonable concrete grade for the green architectural design and can strengthen the scientific management of resources in concrete production.更多还原
