摘要
以激光粒度分析方法对矿渣微粉试样进行了颗粒群分布测试,并以RRSB线性回归进行拟合。对不同类型的矿渣微粉试样,在均匀性系数n、特征粒径x'与勃氏比表面积S三个颗粒群特征参量中,分别确定其一,变化其它参量进行水泥胶砂宏观性能测试,以期考察矿渣微粉颗粒群分布与水泥性能的关系。
The distribution of powder clusters of finely ground slag was measured by means of laser granulometer and was modeled through RRSB linear regression. For different samples of finely ground slag, macro performance test of cement mortar was conducted by changing the two among the three factors of even coefficient n, characteristic particle size x′and specific surface area S while keeping the remaining one as constant. With this method the relationship between the particle size distribution of finely ground slag powder cluster and the cement property was investigated accordingly.
