Difference Between Clinker and Cement

Oct 23, 2021The key difference between clinker and cement is that clinker appears as marble-like nodules, whereas cement is a very fine powder.. Earlier, people did not have sophisticated homes; therefore, they used simple things found in the environment to build houses. But today there are many advanced materials and equipment, which assist in constructions.

INVESTIGATION INTO LOWERING CEMENT CLINKER

Reducing cement clinker with mineral addition has been considered an efficient way of saving energy, lowering CO2 footprint of cement and concrete industries.

Best ways to cut carbon emissions from the cement industry

May 20, 2021Clinker alternatives Producing clinker is carbon intensive. Producing clinker is carbon intensive because of the carbon released by limestone, and because of the energy required in the process. Therefore, emissions may be cut by reducing demand for clinker, such as by substituting it with waste materials like blast furnace slag and coal ash.
