| 摘 要： | 主要研究在热带或亚热带气候条件下,高强混凝土中掺入矿物外掺料后,其抗氯离子扩散性能的变化.结果表明,同时掺入矿渣与硅灰对提高混凝土抗氯离子扩散效果最为明显,且混凝土内氯离子总含量与游离氯离子含量基本呈线性关系.

| Abstract: | The effect of mineral admixtures on chloride diffusion in high strength concrete used in tropic or subtropics areas is experimentally studied.And the rezults show that it is the most obviors effeet for increasing the resistance of concrete to chloride diffusion when adding slag and silica fume together,and in concrete the relationship between the total Cl-content and free Cl-content is generally in linear. |
