Development history and evolution of cement grinding aids. Since the 1930s, cement grinding aids have been used in the cement industry. The earliest patents of the 1930s tested and used powdered mixtures of mineral oil, animal oil and petroleum cracking residues to improve the water resistance of cement products and improve the high early strength and processability of cement.
A cement clinker grinding aid which comprises a styrene-maleic anhydride copolymer (SMA) superplasticiser. The SMA is preferably a type with polyoxyalkylene-based side chains. Use of the grinding aid renders the grinding process more efficient and improves the performance of cementitous compositions in which the cement thus ground is used.

19.10.2018The patent addresses methods for increasing the efficiency of cement and mineral grinding by using sustainable raw materials. The patent relates to methods for improving the efficiency of grinding materials such as clinker and limestone, using glycerol derived from biofuel production, in combination with various grinding additives.
11.05.2015a grinding mill which consumes 60-70% of the total electricity consumption of the cement plant. A grinding mill (Ball Mill) is used to grind the cement clinker into fine cement powder. Grinding Aids are used to improve the grinding efficiency and reduce power consumption. This paper discusses the grinding aids mechanism and
In common Portland cement, particles having a size range from 3 to 35 μm are preferred for all the above-mentioned reasons. The common production indicator of optimal cement clinker grinding is the mass fraction of the size distribution passing through a 0.09-mm sieve. This should range from 90% to 97% of the distribution (Sauman, 1993).
The invention relates to the use of methyldiethanolamine as a grinding aid for cement, and in particular its use as a strength enhancing grinding aid for cement. The compressive strength may be enhanced by the methyldiethanolamine at both at an early stage (1and/or 3 days from the start of hydration) and at a late stage (7 and/or 28 days from the start of hydration).
