Cement Testing Equipment ELE International

Cement is a binding material used with fine aggregate to produce mortar for masonry, or with sand and aggregates to produce concrete. Construction cements are usually comprised of lime or calcium silicate and combined with fly ash. They are categorised as either hydraulic (E.g. Portland cement) or non-hydraulic, depending on their ability to set in water.
