| 水质对Ⅱ型CA砂浆拌合性能的影响及其作用机理(51卷) |
| 英文标题 |
| Influence of water quality on mixing performance of CA mortar used for CRTS II-type slab and its work mechanism |
| 摘要 |
| 研究了水对Ⅱ型CA砂浆常温和高温拌合性能的影响，并结合透射电镜TEM分析了水质影响CA砂浆流动性的作用机理。研究发现水中高价阳离子含量越高，不论常温还是高温CA砂浆的流动性都越差，且损失越快。由机理分析得知，由于水中的高价阳离子与阴离子乳化沥青颗粒周围的负离子发生反应，降低了乳化沥青的稳定性，加速其破乳。 |
