摘要
研究了羟乙基甲基纤维素和乙烯基共聚物2种聚合物干粉对硬化水泥砂浆体积密度和毛细孔吸水率的影响。2种聚合物干粉均能显著改变水泥砂浆孔结构,降低硬化砂浆的体积密度和毛细孔吸水率。羟乙基甲基纤维素比乙烯基共聚物的作用更明显。
The influence of hydroxyethyl methyl cellulose and vinyl co-polymer on the bulk density and capillary water absorption of hardened cement mortars was studied. Both polymer powders greatly change pore structure of the cement mortar, reduce its bulk density and capillary water absorption. Therein hydroxyethyl methyl cellulose plays more important role than vinyl co-polymer.
