Portland cement is the basic ingredient of concrete. Concrete, one of the most widely used construction materials in the world, is formed when portland cement creates a paste with water that binds with sand and rock to harden. The U.S. industry average portland cement, as found by this study, is 91.4 clinker by weight. Table 1 describes the.
The standard Bogue calculation refers to cement clinker, rather than cement, but it can be adjusted for use with cement. Although the result is only approximate, the calculation is an extremely useful and widely-used calculation in the cement industry. The calculation assumes that the four main clinker minerals are pure minerals with compositions.
Cement clinker and finished cement are traded internationally. Cement manufacture is a very energy intensive process and results in the production of large amounts of carbon dioxide (CO 2). The carbon dioxide is chiefly produced when the calcareous raw material is calcined to produce calcium oxide. Generally around 0.5 tonnes.

Cement is a term used today to refer to the fine powdery material left after ‘clinker’ has been ‘milled’. When mixed with water, cement can be used to bind or join (as mortar for example) or, when combined with aggregates and sand, create strong and hard surfaces and structures (concrete).
Natural cement consists mainly of lime, derived from limestone and often combined with volcanic ash. It formed the basis of most civil engineering until the eighteenth century, when the first synthetic cements were developed. 2 The clinker is then cooled and ground to a fine powder in a tube or ball mill. A ball mill is a rotating drum.
