3D打印钼尾矿混凝土性能评价指标体系构建OA

This study analyzes the current research status of 3D-printed concrete performance at home and abroad,identifies the existing problems in the current performance evaluation research of 3D-printed concrete.Based on the statistical analysis results of literature publication volume,the evaluation indicators for the performance research of 3D-printed molybdenum tailings concrete are summarized and induced.The Delphi method is employed to optimize the evaluation indicators,and an evaluation index system for 3D-printed mo-lybdenum tailings concrete performance consisting of 5 first-level indicators and 23 second-level indicators is established.Meanwhile,the acquisition approaches for the evaluation indicators are provided,and the index weight calculation method and comprehensive evalu-ation method are analyzed and determined to enhance the operability of the evaluation index system.This study aims to improve the standardization level of the technical application of 3D-printed molybdenum tailings concrete.
