利用扫描电子显微镜对氯盐侵蚀后不同掺合料混凝土微观形貌进行了观测，从细观角度研究了掺合料对混凝土微观形貌特征的影响。结果表明：①随着粉煤灰、矿粉掺量的增加，混凝土细观结构变的致密，孔隙减少，抗渗性能增强；②掺加粉煤灰和矿粉的混凝土交界面缝隙变小，骨料和水泥浆之间连接紧密，提高了混凝土自身的抗渗性能。

The micro-morphology feature of concrete mixed with mineral admixture after chloride corrosion was studied by SEM ,and the influence of mineral admixture on the microstructure of concrete was analyzed in micro-view.The results showed that ①The mi-crostructure of concrete became dense and pore decreased with more fly ash or slag added which led to a better impervious performance.②The performance of concrete impermeability was improved when fly ash or slag was added ,and the interface apertures became smaller and the connection between aggregate and cement paste became tight.
