Cement grinding aids have been used for improving cement clinker grinding efficiency, power flowability, and strength development of binders. Moreover, cement grinding aids have positive effects on the mechanical properties of cement, such as setting time, compressive strength, surface area, and mortar workability.
Portland cement is usually made from cheap, quarried raw materials, and these usually contain substantial amounts of Cr, Mn and Fe. For example, limestones used in cement manufacture usually contain 0.3-1% Fe2O3, whereas levels below 0.1% are sought in limestones for white manufacture. Typical clays used in gray cement rawmix may contain 5-15% ...

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.
A grinding aid is a specialty chemical agent used to make it easier to grind and mix cement. Specifically, grinding aids prevent cement particles from re-agglomeration, or re-adhering, during and after the grinding process. Grinding aids make it possible to streamline the cement-making process by increasing process efficiency and material fluidity.
