绿色混凝土生产效益能值评价——基于相图表达

Benefit evaluation of green concrete production based on emergy analysis

总结了绿色混凝土生产的3种方式:再生集料混凝土生产方式、粉煤灰混凝土生产方式、循环经济模式的混凝土生产方式,以及各生产方式的系统能值流动,提出了针对各种方式的能值分析方法。分别对3种绿色混凝土生产方式和传统的混凝土生产方式进行了能值相图表达分析,结果表明循环经济模式的混凝土生产方式更具可持续性。

It summarizes three types of the patterns of green concrete production：waste concrete recycling,thermal power plants＇ by-products （ fly ash ） recycling and production model of recycle economy, as well as the energy flow models of the system and proposes for emergy analysis method.It is the example of energy analysis that the production models of green concrete, and the results show that the emergy evaluation method could fully measure the three green concrete models of production and the sustainability.
