Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement …

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.
