| 摘 要： | 采用RCM法测定混凝土试件的氯离子扩散系数,研究石灰石粉单掺以及矿渣和石灰石粉双掺对混凝土抗氯离子渗透性能的影响。试验表明,混凝土中掺入石灰石粉对其抗氯离子渗透不利;矿渣和石灰石粉双掺能有效降低混凝土的氯离子扩散系数,20%石灰石粉和10%~30%矿渣双掺能大大提高混凝土抗氯离子渗透能力。

| Abstract: | The influences of the addition of limestone powder and the mixed addition of limestone powder and slag on the resistance concrete to chloride ion transport are studied,according to RCM method.The results indicate that the addition of the limestone powder was found to have detrimental influence on the anti-chloride ion permeability of concretes.The chloride ion diffusion coefficient of the concrete mixed with slag and limestone powder can be effectively decreased.The anti-chloride ion permeability of concrete mixed with 20% limestone powder and 10%～30% slag can be greatly improved. |

| Keywords: | limestone powder slag chloride ion diffusion coefficient RCM method |
