| 摘 要： | 把对经过热激活处理的煤矸石试样按不同粉磨工艺处理成具有不同颗粒群分布的试样,用激光粒度仪对煤矸石粉体试样进行了颗粒群分布测试,并以Rosin-Rammler线性回归进行拟合。在均匀性系数n,特征粒径De与勃氏比表面积S三个颗粒群特征参量中,分别确定其一,变化其它参量进行煤矸石水泥胶砂宏观性能测试,以期考察煤矸石粉体颗粒群分布与其水泥性能的关系。

| Abstract: | The particle size distributions of gangue powder were investigated byLaser Particle Size Analyzer and linear regressions were made according toanalysis of Rosin--Rammer method. Among homogeneous coefficient n.characteristic particle size De and specific surface area of gangue powder S, onewas kept constant, and the others were varied, then the properties of ganguecement mortar were tested out to study the relationship between the particle sizedistribution of gangue powder and cement properties. |
