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 Smeaton experimented with
quot;Naturalquot; cements corresponding to certain cements of the prePortland era, are produced by burning argillaceous limestones at moderate temperatures. The level of clay components in the limestone (around 3035%) is such that large amounts of belite (the lowearly strength, highlate strength mineral in Portland cement) are formed without the formation of excessive amounts of free lime.
The sources of variations in the properties of portland cement are discussed in this paper as well as the problems that such variations can create; some solutions to these problems are offered. Particular attention is given to the distinction that should be made between the minimum requirements of a general quality specification and the more rigid requirements of a purchase specification.

Buildings, bridges, sidewalks etc., all utilize hydraulic cement and most likely contain it as an ingredient. On its own, portland cement is a caustic material and can cause chemical burns if it comes in contact with skin, so it should be handled with care.
Portland cement consists of four major clinker compounds, C 3 S, C 2 S, C 3 A, and C 4 AF together with the gypsum added during grinding. The relative portions of these compounds can be changed to optimize specific properties of the cement (discussed in more detail below).
Portland cement, an invaluable building material has brought about a revolution in the construction industry. Its dominance over other cements has been due to its strong nature, good hydraulic properties and the ability to carry large proportion of aggregate.
Portland cement is widely used building material in the construction industry. As per ASTM, Portland cement is five types. These types are based on their rate of hydration and sulfate resistant properties. The cement types are: Type I Type II Type III Type IV Type
