纤维素醚在普通干混砂浆中的应用研究

Research on application of cellulose ether in common dry-mixed mortar

研究了羟丙基甲基纤维素醚不同掺量下对普通干混抹灰砂浆性能的影响,结果表明:随着纤维素醚掺量的增加,稠度、密度有所降低,凝结时间有所延长,7 d和28 d抗压强度有所降低,但干混砂浆的整体性能得到了提高。

The paper researches the influence of different mixing doses of the hydroxyl propyl methyl cellulose on the performance of the common dry-mixed mortar, proves by the result that the consistence and density of cellulose ether were lowered and the condense time prolonged, and the pressure resistance strength of 7 d and 28 d lowered somehow along with the doses of the cellulose ether, while the general performance of dry- mixed mortar was improved.
