磷石膏对半刚性基层材料的作用机理

Mechanism on the phosphogypsum-improved semi-rigid basecourse

在试验研究基础上 ,采用 X射线衍射进行定量分析 ,用电镜进行微观结构分析 ,第一次发现磷石膏与火山灰反应产物生成新产物 (单硫型水化铝酸钙 ) 。

This paper,on the basis of tests,employs X ray diffraction method to make qualitative analysis and employs electron microscope to analyse micromechanism,finds the new resultant (3CaO·Al 2O 3·CaSO 4·12H 2O) of phosphogypsum's reaction at first time,and abtains the mechanism on the phosphogypsum improved semi rigid basecourse.
