Influence of Powder Grinding Fineness on Steel-ore-Slag No-clinker Cement Properties

The influence of powder grinding fineness,the particle size distribution,specific surface area on steeloreslag cement properties has been studied in this thesis. The results showed that the improvement of steelslag′s powder grinding fineness can improve the strength of the noclinker cement.As the fineness diminishes,the strength of the cement increases. When the specific surface area increases from 380 m\+2/kg to 517 m\+2/kg and the incising size reduces from 30.2 μm to 24.5 μm, the increasement of the strength is the most obvious.
