在所有的干粉砂浆产品中,无一例外都需要加入甲基纤维素醚,它的最大贡献是增加砂浆的保水能力,改善流动性和施工性,提高水泥砂浆的初期强度和避免开裂,特别在高吸水性基层和高温施工中表现尤为突出。在掺有一定量可在分散乳胶粉的前提下,纤维素醚对水泥砂浆抗折、抗压、拉伸粘结强度的影响规律;通过压汞法测试孔结构,分析研究MC的引入对水泥砂浆孔隙率及孔径分布产生的影响。结果表明,掺了纤维素醚的水泥砂浆拉伸粘结强度有所提高;掺甲基纤维素醚后,水泥砂浆抗折、抗压强度均有所降低,掺量越大,强度越低:掺羟丙基甲基纤维素醚后,随着掺量增加,水泥砂浆抗折强度先增大后减小,抗压强度逐渐减小,最佳掺量宜控制在0.1%-0.3%:水泥砂浆中掺了MC后,孔分布面积增大,小孔数量增多,大孔数量减少,平均孔径减小。
