In our labs, we have been able to develop a new chemical for Cement Additives that not only enhances the grinding and performance efficiency of cements but also increases its compressive strength. It improves the compressive strength of cement tremendously. Increases the grinding efficiency by 7-15% thus increasing the output of grinding mills.

production is related to the use of grinding aids. Cement grinding aids are pro cess additives used during finish grinding in order to reduce cement pack set inside the mill and to increase production. Grinding aids act by coating the particles which cause agglomeration with a mono -molecular layer which neutralizes the

5. Cement grinding. At the cement mills the clinker is mixed with other additives required for producing the specific type of cement. Gypsum for OPC, limestone for limestone cement, and slag for slag cement. The ball mill then grinds the feed to a fine powder. The fine powder is then sent to a separator which separates fine and coarse product.

The limestone acts as a seed crystal for the cement, better distributing the reaction products and increasing the reactivity of the cement. As there is always unhydrated cement in the concrete, this change will have no real measurable effect on the use of fly ash. The cement might have a reduced water demand, and the coarser cement gradation ...
