磷石膏的微量组分及其对水泥凝结、水化和硬化的影响

Micro-components in phosphogypsum and their effects on cement setting, hydration and hardening

借助差热分析、热失重、X射线衍射和扫描电镜等测试手段,分析了磷石膏的微量组分,研究了磷石膏对硅酸盐水泥物理性能及水化过程和水化产物的影响,进而探讨了磷石膏对水泥单矿物的水化作用机理。

By means of DTA, TGA, XRD and SEM, etc.The micro—components in phosphogypsum are analized.Influences of phosphogypsum to physical property, hydration, and hydrated products of Portland cement are studied.The action of phosphogypsum to the hydration of every cement mineral is further discussed.
