A range of materials – often industrial byproducts that would otherwise be waste – can be added to cement to reduce its carbon footprint and support the circular economy. Clinker substitutes – or supplementary cementitious materials (SCMs) – are a wide range of both naturally-occurring and industrial byproduct materials that can be used

1) alite size, as before. 2) C2S content , as before. 3) grinding aid. Cost 0.6-1.2 €/t, usage 150-400 g/t. As the cement particle gets smaller the pores disappear and no longer become a factor. Increasing the amount of grinding aid will make the cement easier to grind. Hard burning = hard grinding.
