  Effect of superfine slag powder on cement properties

  200241 · Abstract. The particle size distribution (PSD) of the dense packing powder and that of actual cement powder was analyzed to explain the packing effect of superfine powder. The degrees of hydration of slag powders with specific surface area ranging from 300 to 800m 2 /kg were calculated to illustrate the enhancement of pozzolanic effect.
