Clinker
Clinker. Clinker is the backbone of cement production. It is essentially a mix of limestone and minerals that have been heated in a kiln and have been transformed by this heat. When limestone is converted to clinker, CO 2 is released (also known as process emissions). A substantial amount of heat is needed to start and sustain the chemical ...

What is Cement Clinker? Composition, Types & Uses
Cement clinker is an intermediary product produced in the manufacturing of Portland Cement. It is solid and occurs as nodules or lumps measuring between 3 mm to 25 mm or 0.12 inches to 0.98 inches in diameter. It is formed by fusing limestone and aluminosilicate materials without melting them to the point of liquefication.

Cement emissions intensity has remained relatively stable since 2018, at just under 0.6 t CO 2 per tonne of cement produced, following several years of modest increase largely due to an increasing clinker-to-cement ratio in China. To get on track with the NZE Scenario, emissions must fall by an average of 3% annually through to 2030.

Clinker is the main ingredient in cement production. Clinker loading and hold cleaning is similar to cement, except that clinker does not contain a binding agent and thus does not harden to the same degree that cement does. Cement clinker is the semi-manufactured material which needs to be ground into powder to make ordinary cement.

Cement production begins with limestone, a sedimentary rock. Once quarried, it is mixed with a silica source, such as industrial byproducts slag or fly ash, and gets fired in a kiln at 2,700 degrees Fahrenheit. What comes out of the kiln is called clinker. Cement plants grind clinker down to an extremely fine powder and mix in a few additives.
