The nature of the raw materials used to produce cement can result in considerable variations in the chemical composition of the final cement. Hence, chemical analysis of cement can be used to find out the quality of cement as well as to identify the exact applications a specific cement type may be suited to.
The sources of raw materials used in the manufacture of Portland cement include pure to argillaceous limestones, shale and clay, plus minor quantities of sand, iron ore, fly ash, coal ash and suitable industrial wastes. To ensure a high quality product, rapid - precise - reproducible and practical analytical techniques are required.
