clinker factor Page 1 of 2 International Cement Review

Nov 10, 2010 Re: clinker factor. The majority of Portland cement clinker manufactured around the world has a lime saturation of between 90 and 100%. 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. The clinker factor is therefore 0.65 x the amount of raw mix.

GB2208857A Flux for cement clinker formation Google

A flux for cement comprises mainly wollastonite. By adding the flux 1-10% in preparing a cement raw material, the firing temperature may be reduced, the firing time may be shortened, coal consumption may be decreased and the productivity of cements may be improved. Also environmental pollution can be reduced and the compression strength and the bending strength of the cement can be improved.

alumina and iron in the finished product, known as cement clinker. Cement is therefore essentially a mixture of calcium silicates and smaller amounts of calcium aluminates that react with water and cause the cement to set. The requirement for calcium is met by using high calcium limestone (or its equivalent calcareous raw material) and clay, mudstone or shale as the source of most of the silica and alumina.
