Effect of high temperature curing on early hydration characteristics and paste structure of complex binder containing slag was studied by the determination of hydration degree,type of hydration pro-(ducts,) as well as micromorphology of hardened paste using calorimeter,XRD,SEM and MIP.The results show that the hydration dormant period is obviously shortened and the activity of slag is activated under high temperature curing.Though high temperature can accelerate early hydration reaction rate,it has little i...
