| 摘 要： | 对TLA灰分和两种对比矿粉的密度、颗粒组成、比表面积、扫描电镜以及X衍射等试验进行分析.分析结果表明,TLA灰分的密度和比表面积明显大于两种对比矿粉的密度和比表面积;TLA灰分的主要成分为硅酸盐火山灰细粉,其粒径最细、分布均匀,表面粗糙、形状不规则,而两种对比矿粉颗粒较粗,分布不均匀,表面光滑、棱角分明.因此,TLA灰分具有很强的吸附作用,对提高TLA改性沥青的性能起着重要的增劲作用.

| Abstract: | The structures and properties of TLA and 2 kinds of comparative mineral filler were studied using the mothod of density,particle composition,specific surface area,scanning electron microscopy and X ray diffraction analysis.The results show that the density and the specific surface area of TLA are obviously bigger than those of 2 kinds of comparative mineral filler.The main composition of TLA is the fine powder of silicate volcanic ash,and its particle sizes are finest and well-distributed.Its surfaces are r... |
