Cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary Some deposits are mined by underground methods Softer rocks such as chalk and clay can be dug directly by excavators
The earliest forms of stoping were conducted with hand tools or by fire-setting; later gunpowder was introduced From the 19th century onward, various other explosives, power-tools, and machines came into use As mining progresses the stope is often backfilled with tailings, or when needed for strength, a mixture of tailings and cement In old .
The Bogue calculation of cement mineral composition A simple estimate of the phase composition of a portland cement can be obtained from the oxide composition if one assumes that the four main cement minerals occur in their pure form With this assumption, all of the Fe 2 O 3 is assigned to C 4 AF and the remaining Al 2 O 3 is assigned to C 3 A
Introduction Sand and gravel are used extensively in construction In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b) Thus, the world’s use of aggregates for concrete can be estimated at 259 billion to 296 billion tonnes a year for 2012 alone

Proportioning of materials Portland cements can be modified easily, depending on the raw materials used and the process used to combine them Proportioning of the raw materials is based on a series of simultaneous calculations that take into consideration the chemical composition of the raw materials and the type of cement to be produced: American Society for Testing and Materials (ASTM) Type .
Cement is seldom used on its own, but rather to bind sand and gravel together Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete Cement is the most widely used material in existence and is only behind water as the planet's most-consumed resource
Cement, or Portland cement, is defined as "a hydraulic cement, obtained by burning a mixture of lime and clay to form a clinker, then pulverizing the clinker into powder The greenish gray powder is composed primarily of calcium silicates, calcium aluminates, and calcium ferrit

Stages of setting of cement, setting times of cement and factors affecting and initial and final setting time of different cements and various processes involved are discussed When water is mixed with cement to form a paste, reaction starts In its pure form, the finely ground cement ,
Chemical Composition of Cement The raw materials used for the manufacture of cement consist mainly of lime, silica, alumina and iron oxide These oxides interact with one another in the kiln at high temperature to form more complex compounds The relative proportions of ,
Most of the balance is lost from the process as carbon dioxide emission to air in the calcination reaction (CaCO3 → CaO + CO2) The cement industry is an energy intensive industry with energy typically accounting for 30-40% of production costs (ie excluding capital costs) Various fuels can be used to provide the heat required for the process
Accurate cement production also depends on belt scale systems to monitor output and inventory or regulate product loadout, as well as tramp metal detectors to protect equipment and keep the operation running smoothly The Cement Manufacturing Process flow chart sums up where in the process each type of technology is making a difference NOTE:
2 Cement Manufacturing Process: The main component of cement is clinker, which is produced from raw materials, such as limestone and clay  Limestone supplies CaCO 3 for the cement production Silica, alumina, and iron are considered to be other raw materials The lime stone used for cement manufacturing contains 75-90 % of CaCo 3
