Influence of Activity of Waste Slag Powder on Slag Cement Strength
As a kind of additional, waste slag may improve cement and concrete durability. However, the influence lies on the slag activity for several original waste slag. In this paper, the influence of activity for different original waste slag on the strength of slag cement was analyzed by using XPS (X-ray photoelectron spectrometer). The results showed that the order of slag cement strength prepared by different slag is T> H> C> J. The combination mode of silicon and aluminum in the waste slag microstructure greatly affect reactive quantity of slag powder, so that the cement strengths are obviously different. And the hydration activity of slag is more when silicon mainly exists in the form of oxide and aluminum mainly exists in the form of aluminates.
