The requirement was to deliver additives for the cement grinding process, which act as high-performance quality improvers, achieving significant increases in resistance levels (around 10% to 15%) and being able to increase the production (minimum in 10%).

Laboratory and industrial tests were carried out with different additives from the SikaGrind® Range, which led to significant improvement oft the grinding system. The specific electrical consumption (kWh/t) was reduced by up to 24%, resulting in an increase of production of more than12 t/h. Parameters such as Blaine, fineness and compressive strength of the cement were improved with the use of the SikaGrind® additives, reflecting a better particle size distribution of the cement and greater efficiency for the entire grinding system.

Based on the optimization process and the quality of the cement, SikaGrind® 720 showed the highest potential to achieve increases in the production ratios. Its use as a grinding aid and quality improver was confirmed.

During 2020 a new product was developed: SikaGrind®-795 PE. With the new product, it was possible to reduce the dosage by 20% while maintaining the quality and operational parameters achieved with the previous product.

SikaGrind®-795 PE is a grinding aid and quality improver for the cement production. It has been designed to produce cements of superior quality with improved strength in all ages.
