摘要
研究了羟乙基甲基纤维素和乙烯基共聚物两种聚合物干粉改性砂浆加水搅拌后的性能。两种聚合物干粉的掺量对其减水率和保水率有着显著影响。羟乙基甲基纤维素对保水率的提高起着主要的作用。
The properties of cement mortar modified by hydroxyethyl methyl cellulose and vinyl co-polymer were studied.Both polymer powders with differents addition amount have great influence on its water reduction and retention.Hydroxyethyl methyl cellulose plays more important role on the improvement of water retention.
