摘要
对混合建筑垃圾骨料砂浆和天然河砂骨料砂浆的物理、力学性能进行了对比研究,结果表明,在胶凝材料用量相同、砂浆稠度相近时,混合建筑垃圾骨料砂浆除吸水率稍偏大外,其抗压强度明显高于天然河砂骨料砂浆,其他物理性能与天然河砂砂浆基本相近,能有效解决城市建筑垃圾的处理难题。
This paper compared and researched the physics,mechanical properties of mixed building waste aggregate mortar and natural sand aggregate mortar,the results showed that in the same amount of gel material,mortar consistency,the mixed building waste aggregate mortar except water absorption rate slightly large,its compressive strength significantly higher than natural sand aggregate mortar,other physical properties similar with natural sand mortar,could effectively solve the process problems of city building waste.
