The cement industry has contributed to an increase in 2 mK temperature since 1990, which is likely to grow up to 14.8 mK by 2050 if no mitigation measures are applied. Energy efficiency improvements by extensions of perform achieve and trade scheme can reduce 0.33 mK from the Indian cement industry.

The Brazilian cement industry has a long history (more than 70 years) in the production of blended cements, with a nationwide average clinker-to-cement ratio below 70%.₅ In Brazil, the most widely used SCM is currently blast furnace slag from steel mills,₆ though calcined clay and fly ash are also in the mix.
The cement mill (or finish mill) presents a convincing case for automation as the optimization process employed by many cement manufacturers is mainly manual. Particle fineness of the cement is measured by way of Blaine measurements, routinely carried out separately off-line. In a conventional setup, peak performance was ensured …
