Sep 03, 2019  One approach to reducing carbon footprint is to use supplementary cementitious materials (SCMs) to lower the clinker factor of cement. Each 1% drop in clinker factor can reduce emitted CO 2 by 8-9 kg/cement tonne. However, increasing the SCM level to lower the clinker factor usually results in somewhat poorer cement

The ever-shrinking clinker factor: Threat or opportunity?

May 01, 2018  The cement industry would rather use cheaper ingredients in its cement than costly (and polluting) clinker, if the cement has the same properties. So, to come to the theme of this ‘Last Word,’ is a reducing clinker factor (the amount or percentage of clinker that is used in cement) a threat or an opportunity for the global cement industry?

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.
