Achieving the "Lowest Clinker Factor" | First

In the intergrinding mode with Clinker +Slag + Gypsum ground together, the clinker (with Gypsum) gets preferentially ground leaving slag relatively coarser, proper optimization of the distribution of slag in desired size fractions of Cement with or without cement additives could help achieve a clinker factor of around 35 to 40 %Improving VRM stability to achieve higher clinker factor reduction However, this leads to a lack of grinding aid in cement to achieve all the benefits from the chemicals This is further emphasised with strength enhancers that are used for their combined properties as process improvers and chemical activators to boost cement strengths InImproving VRM stability to achieve higher clinker
