HEA2® is one of the most effective dispersants yet developed for use as a grinding aid/pack set inhibitor for portland cement and other hydraulic cements. HEA2® greatly improves the efficiency of the grinding process by reducing the surface energy forces which cause agglomeration of the newly fractured cement .
grinding aid (amine based). Summary Besides offering a range of traditional cement additives, Sika has developed and introduced a new generation of grinding aids based on polycarboxylate polymer technology. These new products offer all the positive effects, why grinding aids have been used over the last decades, mainly which
a stronger grinding aid will be a solution provider. Three-fold approach To gather comprehensive knowledge for developing high-performance grinding aids, Sika has followed a three-fold approach: the basis has been the evaluation of the physical and chemical background of forces between cement particles. Then, extensive screening with

While the grinding aids had only a marginal effect on the grinding of quartz, they had a significantly beneficial effect on the grinding of limestone and cement clinker. Triethanolamine appeared to be the most effective of all the aids studied. In the grinding of cement clinker, gypsum also acted as a very effective grinding aid.
Cement Grinding Aid Mechanism in VRM Benefits of Cement Grinding Aid CGA reduces the inter-particle attractive forces of cement which causes agglomeration of cement grains.
IN THE CEMENT PRODUCTION ABSTRACT This is a summary of the use of cement additives 111 the cement production, focusing on the mechanism of action of grinding aids (G.A.). A distinction will be made between pure G.A. and G.A. performance enhancers, that act on the mechaniœal characteristics of the cement.
