The main reason is that steel slag powder, as a relatively more inert powder particle than GGBFS powder, reacts much less than GGBFS powder in the early stage and reduces the production of reaction products, which can delay the setting of the paste. From the SS0 group to the SS10 group, the initial and final setting times increased by 10.5% ...
