Microscopic analysis can provide information of material quality and controlling for analysis of raw material/raw-mix analysis such as;

• estimation of burn ability,
• mineralogy,
• chemistry of size fractions and individual phases,
• efficiency of grinding and
• homogenization processes

The other information from Clinker and Cement examination by microscopic analysis can provide

• the detail information regarding temperature profile; calcining and burning zones of kiln; rate of heating, max temperature, retention time and rate of cooling.
• Accurate investigation in clinker mineralogy can estimate cement performance better.

Prediction of cement performance also can be determined earlier such as

• grinding potential efficiency, potential strength gain and

Impact on additional mineral component on cement such as limestone & fly ash.
