      在所有的干粉砂漿產品中,無一例外都需要加入甲基纖維素醚,它的最大貢獻是增加砂漿的保水能力,改善流動性和施工性,提高水泥砂漿的初期強度和避免開裂,特別在高吸水性基層和高溫施工中表現尤為突出。在摻有一定量可在分散乳膠粉的前提下,纖維素醚對水泥砂漿抗折、抗壓、拉伸粘結強度的影響規律;通過壓汞法測試孔結構,分析研究MC的引入對水泥砂漿孔隙率及孔徑分布產生的影響。結果表明,摻了纖維素醚的水泥砂漿拉伸粘結強度有所提高;摻甲基纖維素醚后,水泥砂漿抗折、抗壓強度均有所降低,摻量越大,強度越低:摻羥丙基甲基纖維素醚后,隨著摻量增加,水泥砂漿抗折強度先增大后減小,抗壓強度逐漸減小,最佳摻量宜控制在0.1%-0.3%:水泥砂漿中摻了MC后,孔分布面積增大,小孔數量增多,大孔數量減少,平均孔徑減小。
