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 ...
