Organic-inorganic composite mortar thickening powders were prepared by adding organic materials and using magnesium slag powder and fly ash as a carrier* and their basic performance and micro-structure were tested. The results show that water retentivity of the organic-inorganic composite mortar thickening powders prepared with magnesium slag are good .and adhesive strength are 1.5 times higher than that of without thickening powder. The prepared organic-inorganic composite mortar thickening powders have dense microstructure* good durability and low cost* and provide technical support for the general promotion of dry- mixed mortar.%分别采用镁渣粉和粉煤灰作为载体,辅以有机材料配制有机-无机复合砂浆稠化粉,对掺稠化粉砂浆的基本性能及微观结构进行测试.结果表明,利用镁渣粉配制的有机-无机复合砂浆保水性好,粘接强度比不掺稠化粉提高1.5倍,微观结构致密,耐久性好,而且成本低廉,该研究为普通干混砂浆的推广提供了技术保障.
