This is a broad overview of the use of cement additives in the cement production, focusing on the mechanism of action of grinding aids (GA). A distinction will be made between pure GA and GA-performance enhancers, that act on the mechanical characteristics of the cement. In the end, the benefits of the use of cement additives have been

Generally speaking, in sulphoaluminate cement, the retarding components are mainly ligneous calcium sulphonate, sugar calcium, boric acid, calcium gluconate and sodium gluconate, the early strength components are Li2CO3, Ca (NO2) 2 and so on, and the water reducing components are mainly polycarboxylate superplasticizer (PC), naphthalene superplasticizer (NSF), melamine superplasticizer
2015-1-1 Mixing with additives. The cement is usually mixed dry with the additives. Depending on the application of the cement, a wide variety of additives can be incorporated. These include accelerators, retarders, dispersants, extenders, weighting agents, gels, foamers, and fluid-loss additives. 10.2.6. Important properties of cement slurries and set
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.

When the water-reducing agent is added to the mortar, the water-cement ratio can be significantly reduced, and the mortar’s good fluidity can be maintained. Generally speaking, the water reduction rate of high-efficiency water reducing agent can reach about 20%, while the water reduction rate of ordinary water reducing agents is about 10%.
2016-10-19 Concrete admixtures (additives) enhances the properties of concrete for applications in construction with special requirements. Concrete additives are used to achieve desired workability in case of low water cement ratio, and to enhance setting
