摘　　要：通过在水泥净浆或砂浆中掺加不同比例的增强掺料 (乳胶、硅粉和甲基纤维素 ) ,比较了各种掺料对水泥砂浆构件强度和对水泥净浆构件阻尼比的影响效果 ,另外初步探讨了各种掺料的作用机理。试验表明 :掺乳胶水泥净浆构件的阻尼比是基准水泥净浆构件阻尼比的 2～ 3倍 ,掺硅粉水泥砂浆构件比基准水泥砂浆构件强度提高 30 %～ 5 0 % 。In this paper,the effectiveness of various fillers (latex,silica fume and methylcellulose)on both the strength of cement mortar components and the damping ratio of cement paste components is compared by filling the cement with these filler.In addition,the function mechanisms of various fillers were discussed.The experimental results show that the critical damping ratio of paste with latex is approximately 2 to 3 times as that of the pure paste.The strength of mortar with silica fume is 30～50% higher than that of the pure mortar,and methylcellulose possesses more of less effectiveness on improving both the strength and damping ratio.
