摘　　要：文章通过对胶凝材料中的水进行划分,研究水泥-石灰-粉煤灰三元胶凝材料体系的水化机理,并通过SEM结合热重-差热分析粉煤灰在熟石灰激发作用下的水化程度。结果表明,石灰能够作为激发剂激发粉煤灰的水化,并得出其最佳掺量,通过SEM佐证了粉煤灰水化程度与龄期之间的关系。Water in the cementitious can be divided from evaporable water and non-evaporable water, by this theory the hydration mechanism of cementitious material made from ternary system material such as concrete,lime and fly ash can be studied. Through the SEM combined with differential thermal analysis,it is found that the slaked lime could accelerate the hydration degree of fly ash. The study shows that: lime could use as an excitation agent to motivate the hydration degree of fly ash, and obtain the best amount. Through SEM method the relationship between the hydration degree of fly ash and the age is proved.
