Cement is a binding material used to produce mortar using fine aggregate or to produce concrete using sand and aggregate.
Construction cements are generally composed of lime and calcium silica and combined with fly ash.
Cements are classified as hydraulic (Portland cement) or non-hydraulic based on their behavior in water.
High quality cement is required for the production of concrete and mortar that meets the relevant building standards.
Cement quality can be determined by performing many quality control tests such as fineness determination, consistency determination, vicat test, compression and feluxural strength, setting time, operability, expansion, hydration temperature and chemical composition.
