摘　　要：为获得炉渣灰在<80μm、80~150μm、>150μm粒径区间的颗粒特征变化规律,通过激光衍射、SEM扫描电镜开展了炉渣灰颗粒的粒径分布试验研究。结果表明:由于炉渣灰易形成蜂窝状的多孔空间结构,导致其细小颗粒易堆积填充,形成粒径大小不一的团聚体,其中>150μm的颗粒团聚现象最为明显。In order to obtain the particle characteristics of slag ash in the range of<80 um,80~150 um um and>150 um,the particle size distribution of slag ash was studied by laser diffraction and SEM scanning electron microscope.The results show that as slag ash is easy to form a honeycomb-like porous space structure,its fine particles are easy to accumulate and fill,and aggregates with different particle sizes are formed.The agglomeration of particles>150 um is the most obvious.
