摘要：

In this paper, the influence of fineness on the cementitious properties of steel slag and the properties of cement containing steel slag with different finenesses were investigated. The results show that increasing the fineness can significantly enhance the early as well as the late cementitious properties of steel slag. However, the early hydrations of cement and steel slag tend to hinder each other especially in the case of large steel slag replacement and high fineness of steel slag. Therefore, increasing fineness of steel slag cannot improve the early cementitious properties of the cement containing steel slag. At 28 days, the hydrations of steel slag and cement tend to promote each other. Increasing the fineness of steel slag enhances the late cementitious properties of the cement containing steel slag significantly.
