预拌砂浆及再生砂浆研究与发展现状

Research and Development Status on Ready-mixed Mortar and Regeneration Mortar

将废混凝土制成再生细骨料并用到工程实际中,对于提高建筑垃圾利用率和环境保护有重大意义。同时,建筑砂浆多在施工现场进行拌制,配合比只能靠经验与人工目测,拌制的砂浆性能往往不稳定,严重时可能存在安全隐患。而预拌砂浆则是由专业化厂家生产,配合比经过计量;砂浆性能均一且满足使用要求。通过对国内预拌砂浆及再生砂浆研究现状分析总结发现,预拌砂浆及再生砂浆的研究已趋于成熟;建议施工方多使用预拌再生砂浆,既有利于施工安全,又有利于环境保护。

Through to the domestic ready-mixed mortar and regeneration mortar research present situation analysis, It is found that research of ready-mixed mortar and mortar has mature; suggested that the construction of more use regeneration ready- mixed mortar, both is advantageous to the construction safety, and is conducive to environmental protection.
