摘　　要：通过对再生建筑微粉混凝土的早期性能、收缩性能、耐久性和力学特性的研究综述,显示再生建筑微粉具有良好的微集料填充效果和火山灰效应,适当的再生建筑微粉可以改善水泥基材料的微观结构,缩短浆体的凝结时间,提高水泥基材料的力学性能和耐久性。利用再生建筑微粉代替部分水泥,有利于降低混凝土制备过程的能耗和二氧化碳,促进行业绿色可持续发展。Through a review of research on the early performance,shrinkage performance,durability,and mechanical properties of recy‐cled building micro powder concrete,it is shown that recycled building micro powder has good micro aggregate filling effect and volcanic ash effect.Proper use of recycled building micro powder can improve the microstructure of cement-based materials,shorten the setting time of the slurry,and enhance the mechanical properties and durability of cement-based materials.Using recycled building micro powder to re‐place some cement is beneficial for reducing energy consumption and carbon dioxide in the concrete preparation process,and promoting green and sustainable development of the industry.
