Our 2050 Roadmap - The 5C Approach: Clinker -

Clinker is produced by heating crushed limestone and a mix of other materials (clay and sand) to 1450 °C in a rotary kiln. Clinker is later ground down to a fine powder and mixed with gypsum and other ingredients to make cement.

Portland cement clinker production using

2019-5-1  Portland cement clinker is typically made by heating, in a rotary kiln, a homogenous mixture of calcaneus (i.e. containing CaCO 3 or other insoluble calcium salts) and argillaceous (i.e. clay-like) materials to a calcining temperature above 600 °C and then fired, normally at temperatures around 1500 °C, to produce a fine powder known as clinker (Sorrentino, 2011).

2020-12-25  Most studies that assess cement CF use a functional unit based on mass measurement units (kgs or tons). However, researchers show that taking other characteristics into account is an equally important approach. The authors [50,51] have shown that accounting for the cement compressive strength in a functional unit affects the results of the LCA study.

The proportions of cement clinker phases produced by the pyro-processing of a raw-material mix are often predicted through the Bogue equations, established in the 1930s; however, the Bogue approach is limited in its applicability. This presents a challenge as the cement industry is seeking innovative and more environmentally friendly cement clinker ...

Cement. Once clinker is produced, it is mixed with gypsum and clinker substitutes which are then ground to the correct fineness to create cement. Importantly, there are no further CO 2 emissions at this stage – however, electricity is used for grinding and mixing, and incoming materials as well as final cement products are transported.
