摘要
XRD定量分析技术,是根据水泥中所特有的粉末微晶物相组合,测试硅酸二钙、硅酸三钙等水泥指示矿物2.78特征谱线变化,精确测定被灌体内外来水泥指示矿物的质量分数,而不受原有岩土矿物所含原地相同化学成份的干扰及影响。通过测定水泥质量分数计算灌浆率,最终确定灌浆量。
XRD quantitative analysis technique based on cement composed of specific power microcline,we menstruated change of 3CaO.SiO2 and 2CaO.SiO2 that cement indicated minerals 2.78 spectral lines,so that we can determine accurately the amount of cement indicated minerals in the talus ,not be influenced and disturbed by original minerals that having the same as composition of cement. By menstruating the content of the cement ,finally we can calculate consolidation grouting rate,then get capacity of consolidation grouting.
