摘要
本文研究了石灰石粉、铁尾矿粉两种掺合料单掺或复掺时对普通硅酸盐水泥抗氯离子渗透性能的影响;并利用SEM方法分析了不同龄期的净浆水化产物。研究表明:在普通硅酸盐水泥浆体中,加入掺合料石灰石粉或铁尾矿粉可以改善水泥浆体的致密性,提高水泥抗氯离子渗透能力;其作用效果为:石灰石粉与铁尾矿粉复掺 > 铁尾矿粉 > 石灰石粉。
In this paper, the effects of limestone powder and iron tailings powder on the resistance of ordinary Portland cement to chloride ion permeation are studied when mixed with single or compound ad-mixture. The SEM method was used to analyze the purification and hydration products of different ages. The results show that in ordinary Portland cement slurry, adding admixture limestone pow-der or iron tailings powder can improve the compactness of cement slurry and improve the re-sistance of cement to chloride ion penetration. Its effect is: Limestone powder and iron tailings powder mixed with iron tailings powder > iron tailings powder > limestone powder.
