Product Description

 

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.[3]

The development of modern Portland cement (sometimes called ordinary or normal Portland cement) began in 1756, when John Smeatonexperimented with combinations of different limestones and additives, including trass and pozzolanas, relating to the planned construction of a lighthouse,[4] now known as Smeaton's Tower. In the late 18th century, Roman cement was developed and patented in 1796 by James Parker;[5] Roman cement quickly became popular, but was largely replaced by Portland cement in the 1850s.[4] In 1811, James Frostproduced a cement he called British cement.[5] James Frost is reported to have erected a manufactory for making of an artificial cement in 1826.[6] In 1843, Aspdin's son William improved their cement, which was initially called 'Patent Portland cement', although he had no patent. In 1818, French engineer Louis Vicat invented an artificial hydraulic lime considered the 'principal forerunner'[4] of Portland cement and, '... Edgar Dobbs of Southwark patented a cement of this kind in 1811'.[4] Portland cement was used by Joseph Aspdin in his cement patent in 1824[3] because of the cement's resemblance to Portland stone. The name 'Portland cement' is also recorded in a directory published in 1823 being associated with a William Lockwood, a Dave Stewart, and possibly others.[7] However, Aspdin's cement was nothing like modern Portland cement, but was a first step in the development of modern Portland cement, called a 'proto-Portland cement'
