再生预拌砂浆综合性能研究进展

Research progresses on the compressive properties of recycled pre-mix mortar

主要结合再生预拌干混砂浆的基本特点、工作性能、力学强度及耐久性能对国内外相关文献研究结果进行了总结与分析,并结合具体工程应用给出了建议。通过调控再生预拌干混砂浆的稠度以及相应的2 h稠度损失和砂浆的保水率来保证干混砂浆的工作性。

Fundamental features,workability,strength and durability of recycle premixed dry mortar have been concluded and analyzed from the literatures at home and aboard,and some remarks are provided for the local engineering applications,the working ability of the regenerated premixed dry mortar is ensured by regulating the consistency of the regenerated dry mortar,the corresponding 2 h loss of consistency and the water retention rate of the dry mortar.
