加气混凝土砌块是国家大力推广和应用的新型建筑墙体材料,针对加气混凝土砌块抹灰砂浆容易出现开裂、空鼓和大面积脱落的问题,笔者利用正交试验的方法,综合研究羟丙基甲基纤维素醚、淀粉醚和聚丙烯纤维对该砂浆性能的影响,从而制备出保水率高、收缩率低和工作性柔和的专用抹面砂浆。 Aerated concrete block is a new type of building wall material widely promoted and applied by the country. In view of the problems of cracking, hollowing and large area falling easily, the author uses the method of orthogonal test to comprehensively study Hydroxypropyl methyl cellulose ether, starch ether and polypropylene fiber on the performance of the mortar to prepare a high water retention, low shrinkage and workability of the special surface mortar.
