摘要
通过激光粒度分析仪(LPS)分析球磨和立磨粉磨的矿渣粉粒度,并用旋转黏度计测定矿渣水泥流变性能及胶砂强度。结果表明:球磨机加工的矿渣粉比立磨加工的矿渣粉颗粒粒度分布宽、细颗粒含量高;矿渣粉比表面积相近时,2种矿渣水泥的流变性能相差不大,球磨矿渣水泥的强度比立磨的稍好。
The particle size distribution of GGBS produced by ball mill and roller mill respectively was studied by means of LPS, the nature of theology 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.
