一种通用型湿拌砂浆外加剂的研究

Study on admixture of a general type of wet-mixed plastering mortar

本文采用抗泥型聚羧酸减水剂(S10D)、引气剂(Y27)、消泡剂(X5)、缓凝剂(H2)、粘度调节剂(CMC)及水等,通过一定比例复配成一种通用型的湿拌砂浆外加剂M300。研究发现,当CMC:S10D:Y27:X5:H2:水=7:3:25:0.5:50:415.5时,可使湿拌砂浆具有良好的和易性及施工性能。并用该样品进行了相关的砂浆试验。试验表明,该复配样品具有适应性好、保水率高、施工性能好等优点。

A general type of wet-mixed plastering mortar was studied by consisting of a mixture of anti-mnd polycarboxylate superplasticizer(S10 D), air-entraining agent(Y27), antifoaming agent(X5), retarder(H2), viscosity modifier(CMC) and water. The results showed that the workability and construction properties of wet-mixed plastering mortar was best when CMC:S10 D:Y27:X5:H2:W=7:3:25:0.5:50:415.5. The developed samples were used to carry out related mortar test experiments. Also, it has good generality, high water-retention capability and fine construction properties.
