Investigation of Cement Pastes and Related Materials by Scanning Electron Microscopy and X-Ray Diffraction.

摘要

Five samples were examined after hydration by scanning electron microscopy (SEM) and both before and after hydration by X-ray diffraction to establish microstructural and compositional data. The majority of the work was done on hydrated material. These samples consisted of three non-expansive cementitious and two expansive cementitious materials. The three non-expansive cementitious materials were an alite, a Type I portland cement, and a Type V portland cement. The two expansive cementitious materials were an ettringite-forming material and a Type K expansive cement.
