In blended cements that contain additions of calcined clay and/or limestone, calcined clay and limestone have higher grindability (softer particles) as compared to clinker (harder particles). Upon intergrinding, clinker tends to remain concentrated in the coarse fraction, which may compromise the early age strength.
