【Abstract】 In this paper, seven kinds of commercial fly ashes in Shanghai Area are collected, the strength properties of cement mortars adding in these fly ashes with various additive amount are measured and compared under condition with same water binder ratio (0.44 & 0.35) and same fluidity. Also, the mechanism of different kind fly ash on strength are analysed.更多还原
