【摘要】 为再生砂替代天然砂用于砂浆提供理论依据,系统研究了建筑垃圾再生砂不同种类和掺量对砂浆性能的影响。结果表明,不同种类的再生砂对砂浆性能影响差别不大;随再生砂掺量的增加,砂浆用水量、收缩增大,但保水性提高,并且对强度没有显著影响;废混凝土再生砂浆的现场抹灰效果良好。更多还原

【Abstract】 The need of huge volume of sand and the available natural sand is limited are contradiction.Large number of construction waste is produced with the process of urban construction.In this paper,impact of type and volume of recycled sand produced by construction waste on mortar performance is researched,it provides the theoretical basis for recycled sand replacing natural sand in the mortar.更多还原
