Grinding aids are organic compounds that are added to the mill during cement grinding. Their main purpose is to reduce the energy required to grind the clinker into a given fineness. In addition, some products (usually referred to as performance enhancers) provide positive effect on cement hydration improving strength development [1]

Dec 01, 2015 Cement quality tests, which were assessed by measuring the compressive strength, implied that TIPA had the highest improvement in 28-days strength with 18.8% at 700 g/t where 8.9% and 5.6% increase were achieved for glycol-based and TEA-based grinding aids respectively. As a conclusion of the study, TIPA based grinding aid was found to be the
