| 摘 要： | 研究了一种外加剂与矿渣、粉煤灰对水泥净浆结合氯离子性能的改善作用.研究结果表明,与粉煤灰、矿渣相比,该外加剂能显著提高单位水泥浆体结合氯离子的性能,且浆体结合氯离子的能力随外加剂掺量的增加而增强;外加剂与矿渣双掺可进一步提高单位浆体结合氯离子的能力;单位浆体结合氯离子量受环境温度以及氯离子浓度等因素的影响.

| Abstract: | Effects of an admixture, fly ash and slag on chloride ion binding of cement paste were investigated by experiments. Results indicate that chlorides binding of unit paste can be improved by addition of fly ash and slag. However, compared with fly ash and slag, the chloride ion binding of unit paste can be greatly enhanced by addition of this admixture and increases with the increase of amount of admixture. Furthermore, coupling with slag and admixture, chloride binding of unit paste can be furtherly enhanced. In addition, chloride ion binding of unit paste will be influenced by ambient temperature and chloride ion concentration. |

| Keywords: | cement paste chloride ion binding admixture temperature |
