Clinker is often replaced with supplementary cementitious materials (SCM) such as granulated blast furnace slag, natural pozzolanes and fly ash in order to reduce CO 2 emissions and material cost. However, SCM may counteract strength development, powder flowability, mortar workability and durability, which are critical for cement quality.
