摘　　要：以保水剂、粘结剂、聚合物纤维对特细砂水泥砂浆综合改性,配制施工性、粘结性、抗裂性良好的加气混凝土特细砂干拌抹灰砂浆。研究了甲基纤维素醚(MC)对特细砂抹灰砂浆保水性、粘聚性、施工性的改性作用;不同纤维对抹灰砂浆的增强作用,聚丙烯纤维的增强效果与掺用方法;粘结剂的改性作用与适宜掺量。分析讨论了加气混凝土特细砂干混砂浆的改性原理及该抹灰砂浆的配制方法及其性能。Dry-mixed superfine sand mortar for plastering aerated concrete with good workability, adhesive capacity and crack resistant was prepared by integrative modification with water retention agent,adhesion agent and polyfibre. Study has been made on modification effect of methyl cellulose ester （MC） on water retentinn,cohesion and workability of superfine sand mortar for plastering,different fiber on enhancement of plastering mortar, enhancement effect and adding method of polyptopylene fiber and modification effect and proper content of cohesion agent. Modification mechanism of dry-mixed superfine sand mortar for plastering aerated concrete,its preparation method and performance have been analyzed and discussed.
