摘　　要：以矿渣微粉浆液、水玻璃溶液和PVA溶液为主要原料,按不同比例复配制备得到建筑垃圾再生骨料改性剂。主要探究了不同配比的改性剂对建筑垃圾再生骨料饱和吸水率和压碎指标的影响,并对其表面微观形貌分析和改性机理进行了分析。综合考虑吸水率和压碎指标,确定的改性剂最佳配比为:10wt%矿渣微粉浆液、5wt%水玻璃溶液与10wt%PVA溶液。This experiment uses micro slag slurry,water glass solution and PVA solution as the main raw materials,prepares the recycled aggregate modifier according to different proportions,studies the effects of different propor tions of modifiers on the saturated water absorption and crush index of recycled aggregate of construction waste,and analyzes its surface micro-morphology and modification mechanism.Considering the water absorption and crush in dex,the experiment provides the best ratio of modifier:10wt%micro slag slurry,5wt%water glass solution and 10wt%PVA solution.
