| 摘 要： | 用Ｘ射线衍射分析（ＸＲＤ）、扫描电镜与能谱（ＳＥＭ－ＥＤＳ）和压汞法观察了氟石膏粉煤灰胶结材的水化产物和硬化浆体结构，并用这种胶凝材料配制出长期强度高的混凝土。氟石膏粉煤灰胶结材的水化产物为二水石膏、ＣＳＨ凝胶及钙矾石。微晶状的二水石膏和钙矾石与ＣＳＨ凝胶均匀混合，形成致密的硬化浆本结构，使胶结材获得优良的力学性能。

| Abstract: | The hydration products and the hardened paste structure of the fluorgypsum fly ash binder were
investigated with XRD, SEM EDS and MIP. The high strength concrete was prepared with this
binder. The main hydration products of the binder are gypsum solid solution, CSH gel and
ettringite. They intermix uniformly to form a dense paste structure. Thus excellent mechanical
properties are obtained. |
