再生骨料指标体系研究

摘要

根据文献试验数据建立了再生骨料数据库.建立了包括三个输入神经元(净水灰比、压碎值和吸水率)和1个输出神经元(抗压强度)的BP网络.提出了压碎值、吸水率等关键指标的规范建议值.%Recycled aggregate database was founded according to experimental results excluded from references. An Artificial Neutral Network was then established to analyze influences of indexes of recycled aggregate on compressive strength of recycled concrete. Key indexes including water absorption ratio and crushing value were finally proposed.
