The final manufacturing stage at a cement plant is the grinding of cement clinker from the kiln, mixed with 4-5% gypsum and possible additives, into the final product, cement . In a modern cement plant the total consumption of electrical energy is about 100 kWh/t . The cement grinding process accounts for approx. 40% if this energy consumption.
Cement industry is characterized by sizeable energy demand which accounts for about 110kWh (3.75 thm) per ton of cement in modern plants. Industry impacts heavily also on CO2 emissions.
The influence of the GAs incorporation in cement grinding on properties such as workability and setting times of the placed concrete and/or mortar has been covered in this review.

The repose angle, collapse angle, and compression degree of cement clinker changed significantly after adding grinding aid. After adding the No. 1 grinding aid, the strength of cement mortar increases. When the dosage is 0.035%, its strength increases significantly. Compared with the control group, it increases by about 10Mpa.
Triethanolamine is considered a popular grinding aid. Its effects on cement characteristics depend on the type of cement and dosage. An addition of 0.025% of Triethanolamine to Portland cement, acts as a set accelerator, at 0.25% as a mild set retarder, at 0.5% as a severe retarder and at 1% as a strong accelerator. ...
