We make cement grinding aids. The system consists of various inorganic sands, glycols, water and Limestone. We need defoamers to quell the foam creation of glycols in water. For such system we recommend a polymeric defoamer like BYK-014 or BYK-1710. I need to stabilize a waterborne, alkaline slurry of light weight microspheres or other fillers.
Many research workers have used additives either as grinding aids for clinker or improving the properties of cement. Effect of additives on individual components of cements have been studied (1-6) extensively to know the hydration behavior.
Other additives sometimes used are ethylene glycol, oleic acid and dodecyl-benzene sulphonate. The heat produced by the clinker is circulated back to the kiln to save energy. The last stage of making cement is the final grinding process. In the cement plant, there are
Additives for concrete admixtures . RS-series is an additive for concrete admixtures designed to save production cost for all type concrete admixtures (PCE, PNS, Lignin base admixtures) by mixing RS-series with admixtures.
