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. Chemical Composition of Cement The raw materials used for the manufacture of cement consist mainly of lime, silica, alumina ... grinding. Table 1.4 shows the approximate oxide composition limits of ordinary Portland cement. ... modern cement is about 45 per cent and that of C2S is about 25 per cent.

The grinding aid composition comprises: an alkanolamine compound that is a primary alkanolamine compound, a secondary alkanolamine compound, or a mixture thereof; and a glycol. Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice, however, clinker composition is largely determined by the compositions of the locally-available raw materials which make up the bulk of the raw meal.

 · A grinding aid is a specialty chemical agent used to make it easier to grind and mix cement. Specifically, grinding aids prevent cement particles from re-agglomeration, or re-adhering, during and after the grinding process. Grinding aids make it possible to streamline the cement-making process by increasing process efficiency and material fluidity. The use of a good Cement clinker grinding aid can be vital in today’s increasing material demands. Along with the obligation to process increasingly larger quantities of ores containing finely disseminated minerals, our limited energy resources and the rising costs of energy present a challenge to the process engineer. One research route that has been explored for about half a century is the ...
