Cement additives are materials added to cement for the optimization of the cement properties and the cement grinding process. Cement additives are classified into different product groups such as grinding aids, strength enhancers and performance enhancers.
Grinding aids are used in order to reduce the electrostatic forces between cement particles and their agglomeration. Grinding aids most commonly consist of ethanolamines such as triethanolamine (TEA) and triisopropanolamine (TIPA) along with glycols such as diethylene glycol (DEG) and propylene glycol (PG).
