| 摘 要： | 根据我国南北方酸雨的pH值和离子组成配制了硫酸型模拟酸雨溶液,采用干湿交替周期浸泡的试验方法来研究不同水灰比下酸雨溶液对水泥砂浆试件抗酸性能的影响。试验结果表明:在酸雨侵蚀下,水泥砂浆质量溶蚀百分数与水灰比呈一元线性关系。水灰比为0.6的水泥砂浆抗折强度降低最为明显,而水灰比为0.5的水泥砂浆抗折强度下降最小,合理的水灰比为0.45~0.55。

| Abstract: | Based on the pH value and ion composition of acid rain in north and south areas of China,solution of simulating acid rain is prepared,which is used to study the influence of water-cement ratio on the acid resistance of cement mortar in the way of the alternation of wetting-dry sulfate corrosion.The results show that the percentage of quality erosion has a good linear relationship with the water-cement ratio;at the water-cement ratio of 0.6,the flexural strength of cement mortar declines most significantly,w... |
