Cement additives are chemicals that are used to improve cement grindability and/or performance. This is accomplished by addressing several challenges in the production of cement. For example, as cement grinding progresses and grains become smaller, the attractive thermodynamic, physical, mechanical and chemical forces result in strong adhesion of particles.
Apr 29, 2020· Grinding aid is a chemical agent used to make it easier to grind and mix cement. The grinding aid began to gain popularity in the mid-20th century as a reliable tool for cement processing. Its effectiveness and reputation for reliability lie in its ability to reduce surface tension between cement particles brought on by the stress of the grinding process.
The grinding aid composition comprises: an alkanolamine compound that is a primary alkanolamine compound, a secondary alkanolamine compound, or a mixture thereof; and a glycol
Description. 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 particles.
The cement grinding aids is additional material in liquid or solid form, admixed in small amount during the cement clinker grinding process which can significantly improve the grinding efficiency and reduce energy consumption, without compromising the performance of the cement. The cement grinding is an energy intensive process. The addition of grinding aid during the

The addition of grinding aid during the process of cement grinding, results in improvement of the specific surface and grind-ability of the material ground. This is attributed to the additive’s ability to reduce resistance to comminution and to prevent agglomeration of the freshly ground particles (due to neutralization of static charges) and

May 11, 2015· History of Grinding Aids • The history of cement additives goes back to the 1930s. • Attempt was made to disperse carbon black in concrete with the help of triethanolamine to solve mottling issue and to improve the strength of concrete. This chemical is given name “Tucker’s Dispersion Aid”.
The grinding aid effect of cement grinding aids is generally affected by the following factors: (1) the nature of the grinding aid material itself. The main components of the grinding aid are generally surface active substances, and the type and molecular weight of the constituent groups affect the adsorption and dispersion properties of the
