White cement is same as that of grey Portland cement but the only differ is in the colour and fineness. This colour of this cement is determined by its raw materials and the process of manufacture. In this article we study about manufacture, properties, uses and difference of white cement. Contents:Manufacture of White CementFollowing Raw material […]
Clinker is a dark grey material with 3 to 25 millimeters in diameter and is produced by heating clay and limestone in the temperature of 1400°C to 1500°C.
Clinker Cement; 1: Clinker is a nodular material which is used as the binder in cement products. Cement is a binding agent that sets and hardens to adhere to building units such as stones, bricks, tiles etc. 2: Clinker is a granular substance containing spherical pellets of diameter 3-25 mm.
Clinker is a dark grey material with 3 to 25 millimeters in diameter and is produced by heating clay and limestone in the temperature of 1400°C to 1500°C. It can be kept in stores for a long time without any change in its quality.
After the clinker is cooled, cement plants grind it and mix it with small amounts of gypsum and limestone. Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects.
Portland cement clinker - overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.
Cement clinker dust (CKD) is a problematic waste derived from the cement industry which may cause some problems in clinkering kiln operations and cement performance. CDW has to be discarded despite its hydraulic properties due to high content of chlorine, sulphur and alkalis.
Dangote Cement has put Nigeria on the world map with the exportation of 27,800 metric tonnes of clinker to a neighbouring African country, reaffirming its status as Africa's biggest cement producer.
The cooled clinker is then conveyed either to the clinker store or directly to the clinker mill. The clinker store is usually capable of holding several weeks' supply of clinker, so that deliveries to customers can be maintained when the kiln is not operating. Get a Better Understanding of Cement
Oct 23, 2011· Cement is an important substance that we use in constructions as a binder to adhere materials to other materials. Clinker is a component in cement. It is the active binding component in cement. Therefore, the key difference between clinker and cement is that clinker appears as marble-like nodules, whereas cement is a very fine powder.
Nov 10, 2010· Re: clinker factor. The majority of Portland cement clinker manufactured around the world has a lime saturation of between 90 and . This means that c.1.55 tonnes of raw mix are required and c.0.55 tonnes of CO2 are lost due to calcination of the CaCO3 in the raw material.
Ordinary Portland Cement Clinker is the core component in producing cement which is formed by sintering limestone. In the manufacturing of Portland cement, clinker formed by sintering or fusing together without melting to the point of liquefaction, alumina-silicate materials such as clay and limestone during the cement kiln stage and happens as 3 millimeters (0.12 in) to 25 millimeters (0.98 ...
Cement manufacturing has several opportunities for WHR, specifically in the process step where the clinker material is produced. For clinker production, a mixture of clay, limestone, and sand is heated to temperatures near 1500°C. The kiln and clinker cooler have hot exhaust streams where waste heat could be recovered.
Artificial cement is manufactured by first burning at a really high temperature that the mixture of calcareous mostly calcium carbonate) and argillaceous ( mainly clay) then grinding the calcined goods, i.e. (clinker) with small amount of gypsum to a fine powder called cement.
Oct 08, 2019· The clinker, after discharge from the kiln and cooling, is ground to a fine powder (not less than 1600 cm2/g specific surface). During this grinding process, a retarder (usually a few percent of gypsum) is added to control the rate of setting when the cement is eventually hydrated. The resulting fine powder is portland cement.
Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln. ...
Cement is a powdery material used in construction projects, while clinker is used for manufacturing cement. Clinker is produced in kiln during the process of manufacturing cement. When raw materials inside the kiln are heated, the temperature rises and reaches its peak, then by rapid cooling, clinker .

The incombustible residue, fused into an irregular lump, that remains after the combustion of coal. ... the "Group"), the largest and the most competitive cement, clinker and concrete producer in Southern China ...
The clinker-to-cement ratio (percentage of clinker compared to other non-clinker components) has an impact on the properties of cement so standards determine the type and proportion of alternative main constituents that can be used. To ensure the future use of other constituents, the cement industry is dependent on the local supply of these ...
Higher the AM, lighter the color of clinker (cement). Normal range of SM is 1-2.5. MgO is commonly present in raw meal. Some of the MgO (2%) is accommodated into the clinker mineral structure, while as extra MgO forms a crystal called periclase and causes mortar expansion. MgO up to 4 % is found common in clinker.
