| 摘 要： | 为改善砌体抹面砂浆的耐水性和耐久性,采用矿物掺和料和有机聚合物防水剂克汰对普通水泥砂浆进行复合改性.以矿粉、粉煤灰、硅灰、克汰掺量为影响因素,以体积质量、软化系数、力学性能和吸水率为指标,进行对比试验研究.结果表明,复合改性砂浆的性能比普通砂浆有明显提高,当掺入5%硅粉、15%粉煤灰、10%矿粉和7 L/m3克汰时,28 d抗压强度提高16.88%、28 d抗折强度提高19.36%、28 d的24 h吸水率降低48.2%.

| Abstract: | In order to improve the water resistance and durability of plaster mortar,normal cement mortar is modified by incorporating mineral admixture and a polymer water repellent(Caltite).The proportions between blast furnace slag,fly ash,silica fume and Caltite were taken to be the influencing factors,and the bulk density,softening coefficient,mechanical performance and water absorption coefficient were applied as evaluation indexes,comparison experiments were conducted.The results show that the properties of the... |
