摘要：研究了可再分散乳胶粉、纤维素醚、消泡剂和硼酸掺量对ALC墙板专用薄层砌筑砂浆性能的影响。结果表明：纤维素醚的掺入可显著增大薄层砌筑砂浆的保水率，但对28 d抗压强度有较大负面影响；相比于纤维素醚，可再分散乳胶粉更能显著提高薄层砌筑砂浆的粘结性能，当可再分散乳胶粉掺量为0.8%时，14 d拉伸粘结强度为对照组的4.5倍；消泡剂与纤维素醚复掺时，能在一定程度上减小抗压强度的降幅。

Abstract：Effects of redispersible latex powder，cellulose ether，defoamer and boric acid on properties of thin-layer masonry mortar for ALC wallboard were studied. The results show that the incorporation of cellulose ether can significantly increase the water retention of thin layer mortar，but has a great negative effect on the 28 d compressive strength. Compared with cellulose ether，the redispersible latex powder can significantly improve the bond performance of thin layer mortar. When the rubber powder content is 0.8%，the 14 d tensile bond strength is 4.5 times of the blank group. When defoaming agent is mixed with cellulose ether，the reduction of compressive strength can be slowed down to a certain extent.
