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]

Composite cement grinding aid is by a variety of single component and grinding aid distribution, and the interaction of different monomer component, to make composite grinding agent has good grinding effect, good stability, wide adaptability of multiple effect. 2. Experiment. 2.1 Experiment Material

Keywords: Cement grinding aid, Fineness, Compressive strength, Size distribution. Abstract. In this paper, By choosing four kinds of grinding aids better one-component, The grinding aid of cement grinding aids is determined by orthogonal optimization. By adding different inorganic reinforcing components, Developed a cement grinding

impacts of grinding aids Grinding aids and strength enhancers are well known for their ability to increase cement mill productivity, and the mechanical strength of mortar and concrete. However, little information is available on the potential drawbacks of their usage. To close the gap Sika

particularly in the grinding of Portland and limestone cements. Production increases generally vary between 10% and 30%, depending on the fineness of the cement, on the grinding system available, on the clinker mineralogical composition, on the additive dosage etc. Specific formulations are available for limestone cement and
