LCA of cement - Appropedia: The sustainability wiki

May 10, 2021  The main component of cement is called clinker. Clinker consists of cinder lumps formed by heating limestone, bauxite, and iron ore sand to 2,770 o Fahrenheit. The production of clinker is very resource intensive. Producing one ton of clinker requires an energy input of between 3000-6000MJ and approximately 1.6 tons of raw material.
