矿渣粉的粉磨方式对矿渣水泥性能的影响研究

Blast furnace slag powder by different grinding methods affecting cement property

通过激光粒度分析仪（LPS）对球磨和立磨粉磨的矿渣粉粒度分析，旋转粘度计对矿渣水泥流变性能的测量及胶砂强度测定。结果表明：球磨机所加工的矿渣粉比立磨加工的矿渣粉颗粒尺寸分布宽、细颗粒含量高：矿渣粉比表面积相近时，两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 blast furnace slag powder ground by ball mill and LM was analyzed by means of LPS, the rheology was measured by NXS and strength was determined by GB.The results showed that the particle size distribution made by ball mill was wider and higher fine particle than LM; the difference in theology was not obvious for two kinds of grinding slag powder under the same specific surface area; And the cement strength for ball mill slag was little better than LM.
