Although limits have been suggested, it is assumed that this is to limit the dolomitic content in the limestone. 7.1.3 Cement blends for cement and concrete testing Two reference cements containing only clinker and gypsum were obtained, both milled without the addition of grinding aid so as to limit the introduction of another variable.
During the grinding of OPC clinker, the grinding aids are added with the ratios 0, 0.03, 0.04 and 0.05 wt.% of the clinker. OPC-limestone blended cement (PLC) are prepared by replacement 5 and 10 wt.% of OPC by limestone. Two percentage of the grinding aids are added to PLC, 0.03 and 0.04 wt.%, during the grinding process.

To ensure an efficient grinding aid application, the impacts of additives on particle and bulk properties, which influence the micro-processes inside the mill, need to be understood. Within this study the effects of several grinding aids on dry fine grinding of limestone in a laboratory vibration mill were investigated.
In either case, the benefits of any grinding aid must outweigh its cost; furthermore, the grinding aid should have no detrimental effect on downstream processing or the finished product. Given these constraints, the firm industrial acceptance of grinding aids in the cement industry that followed over 10 to 15 years must be considered relatively ...
