Effect on property of cement blended with different GGBS ground by ball mill and roller mill respectively

The particle size distribution of GGBS produced by ball mill and roller mill respectively was studied by means of LPS,the nature of rheology and strength of slag cement was measured by NXS.The results showed that the particle size distribution of the cement made by ball mill had wider and higher fine particle content than that of roller mill;the difference in rheology was not obvious for two slag with a samilar specific surface area;and the strength of cement blended with ball mill slag was a little higher than that of roller mill.
