摘　　要：采用扫描电镜分析研究了粉煤灰陶粒混凝土和普通混凝土的粗骨料与水泥石界面组成及结构;研究发现,轻骨料与水泥石界面致密,水泥及粉煤灰掺合料水化完全。从混凝土的微观结构入手,对粉煤灰陶粒混凝土的耐久性能做了分析,并通过抗碳化试验和抗弯曲疲劳试验对其耐久性能做进一步阐述。The combination and structure of interface between coarse aggregate and cement paste of sintered fly ash concrete and common concrete were studied by using scanning electron microscopy; The results show that the combination between lightweight aggregate and cement paste is compact, the hydration of cement and mineral admixture is complete. Begin with concrete microstructure, the article studied on durability of sintered fly ash concrete, and made a further research on the durability by the experiments of carbonation resistance and fatigue.
