Phase Analysis of Portland Cement by Combined …
SEM/XMA of cementitious materials has been given recently [9], so those procedures will be described much more briefly here. Both XRD and SEM/XMA are used to characterize and compare three commercial portland cements. Microstructure imaging and image analysis have always had—and likely will continue to have—a partially subjective aspect.

Basic chemistry
The weight (relative atomic mass) of sodium is 23 and of chlorine is 35.5. If we add these together we get the formula weight of a sodium chloride molecule: 23+35.5=58.5. So, the proportion of sodium in sodium chloride is: 23/58.5 x = 39.3% by mass. The proportion of chlorine in sodium chloride is: 35.5/58.5 x = 60.7% by mass.
Cement microscopy
Most cement microscopy is done using a petrographic microscope. Usually the specimen is a polished section of cement clinker examined using reflected light, although it may be a powder mount or a thin section examined using transmitted light. A scanning electron microscope (SEM) may also be used. The combination of SEM with X-ray microanalysis ...
