G. Habert, in Eco-efficient Construction and Building Materials, 2014. Energy efficiency. Energy demand in clinker production has been significantly reduced over the last few decades. The theoretical minimum primary energy consumption (heat) for the chemical and mineralogical reactions is approximately 1.6–1.85 GJ/t (Klein and Hoening, 2006).However, there are technical reasons why this …

Cement clinker - Wikipedia

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 kiln stage.
