    OverviewHistoryCompositionManufacturingSetting and hardeningUseTypesSafety issues

    Portland cement was developed from natural cements made in Britain beginning in the middle of the 18th century. Its name is derived from its similarity to Portland stone, a type of building stone quarried on the Isle of Portland in Dorset, England. The development of modern Portland cement (sometimes called ordinary or normal Portland cement) began in 1756, when John Smeatonexperimented with combinations of different limest
