What is Cement Clinker? Clinker Definition, Composition ... composition of clinker in cement, Clinker is a nodular material produced in the kiln stage during the production of cement and is used as the binder in many cement lumps or nodules of clinker .Effect of clinker composition on grindability .EFFECT OF CLINKER COMPOSITION ON GRINDABILITY George R ...
Aug 27, 2015· Cement. The mixture of ingredients should be intimate and they should be in correct proportion. The calcined product is known as the clinker. A small quantity of gypsum is added to the clinker and it is then pulverized into very fine powder which is known as the cement.
cement clinker and gypsum but also have the addition of another material. Some additions become hydraulically activated as they react with the Portland cement clinker. To mention a few: Blastfurnace slag cement is a cement made by grinding together portland cement clinker and granulated blastfurnace slag in the proper proportions.
Once cooled, clinker is ground with gypsum and other minerals, such as limestone, to produce the grey powder commonly recognised as cement. Changing the chemical composition of the raw mix enables cements with different properties to be produced for different uses.
The clinker is very finely ground to produce portland (hydraulic) cement. A small amount of gypsum is added during the grinding process to control the cement's set or rate of hardening. Connect. Concrete Alberta. 4944 Roper Rd NW. Edmonton, AB T6B 3T7. P: . F: .
A first approximation of the chemical composition required for a particular cement is obtained by selective quarrying and control of the raw material fed to the crushing and grinding plant. Finer control is obtained by drawing material from two or more batches containing raw mixes of slightly different composition.
The effect of cement composition on cement strength has been studied extensively. 148, 154, 161, 239–250 It appears that this effect is a rather complex one and depends on a variety of factors such as the mutual ratios of clinker minerals, the amount and form of added calcium sulfate, and the presence of minor oxides. The available experimental data may be summarised as follows.
The gap between domestic production and consumption was filled in 2012 by over seven million metric tons of imported cement and cement clinker. Over 80 percent of cement and clinker imported in 2012 came from five major countries: China, Canada, Columbia, Mexico, and the Republic of Korea.
Raw material preparation: grinding a mixture of raw materials to make a 'raw mix'. Clinker burning (Pyroprocessing): heating the raw mix to a sintering temperature of >1400°C in a cement kiln to produce 'clinker'. Cement preparation: grinding the resulting clinker with .
It is generally added in very small amounts (about 2% by weight) to the burnt cement (called Clinker) after it is taken out from the kiln and before it is sent for grinding. Gypsum is a sedimentary rock having a composition of calcium sulfate (Ca SO 4. 2 H 2 O). It is added for imparting a retarding effect in the setting of cement.
Cement Production – The manufacture of cement is a twostep process, notably, clinker production and cement grinding. In the first step, the raw materials are fed to the kiln system to produce clinker.
Portland cement usually consists of portland cement clinker and a sulfate carrier, usually gypsum. Portland cement clinker is prepared from a raw material mixture that contains mainly defined percentages of calcium oxide (CaO), silicon dioxide (SiO 2 ), alumina (Al 2 .

Chemical Composition of Portland Cements. The raw materials used in the manufacture of Portland cement consist mainly of lime, silica, alumina and iron oxide. The oxides account for over 90% of the cement. The oxide composition of (ordinary) Portland cement may be expressed as follows:
