A description is provided of the use of an additive including polycarboxylate ether and/or lignosulfonate as grinding aid in cement grinding for producing a cement, especially when fly ash and rock flour are used in the cement.
MasterCem cement additives amplify grinding efficiency, resulting in a higher mill throughput and lower the clinker factor, with an overall reduction in CO2 emissions. Our performance enhancers modify and elevate cement's properties, improving its strength, workability and flow and ultimately upgrading cement's usability and durability.
Katsioti and colleagues [2] evaluated six commercial grinding additives used in the production of Portland cement. In this study, in all cases, the addition of grinding aid resulted with the development of the specific surface and the grindability index.
Cement additives are chemicals that are used to improve cement grindability and/or performance. This is accomplished by addressing several challenges in the production of cement. For example, as cement grinding progresses and grains …

The OPTEVA® CBA® series of additives is a new concept in grinding aids - significantly different from any previous GCP product for the cement industry. The difference is that it is a "Grinding Aid Plus". OPTEVA® CBA® additives offer all the benefits of traditional grinding aids, such as increased grinding efficiency and cement flowability. In addition, they offer a unique ability to ...
Cement additives are, without doubt, highly beneficial in the production of cement. They are widely used to increase cement mill output and decrease specific energy consumption. Strength enhancing additives can be applied to improve cement quality and also to reduce the clinker factor. To prevent any unwanted effects, it is
and the use of suitable cement additives becomes mandatory. Several types of products can be found on the market. Whatever is the additive used (pure grinding aids, specifically designed to increase production and fineness, or performance enhancers with effect on cement hydration),

Additives have been used in cement grinding since the 1930s. Initially, the main purpose of their use was to increase the production rate, whereas substances which additionally raise the strength of the cement have increasingly come into use from the 1970s onwards [1].
All of the fatty acids used increased the fineness as compared with the cement without the grinding additives. SO and OA decreased the strength significantly, LA decreased it to a lesser extent and SA increased it definitely according to the common cement. But MA did not alter the strength of the cement as much as SA.
