Cement is used to bind together the elements that make up concrete (sand, gravel), the world's most widely used manufactured material (IEA, 2022). Through the decomposition and calcinating limestone in a rotating kiln heated up to 1,450°C, clinker is produced, the binding agent in cement. The clinker is then ground with sand and gravel to create cement (IEA, 2022).
