Compressive Strength • TIPA increase 7 days and 28 days compressive strength of cement • Optimum dosage is 001002% for the enhancement of strength by TIPA • If dosage>optimum dosage it can CHRYSO ® Reductis 50 reduces significantly the Hexavalent Chromium content in cement even at low dosages It allows to maintain durably the Chromium VI content below 2 ppm to be in line with the 2003/53/CE European standards Limited installation and maintenace costs CHRYSO ® Reductis 50 is a liquid solution easy to introduce through aCement Additives Chryso Group
triethanolamine (TEA) as the most popular grinding aid in cement industry, it has been known that the exact action on cement pastes is very complex and depending on the type of cement and the amount of TEA, it behaves differently An addition of 002 % of TEA to Portland cement, acts as a set accelerator, at 025 % it acts as1) alite size, as before 2) C2S content,as before 3) grinding aid Cost 0612 €/t, usage 150400 g/t As the cement particle gets smaller the pores disappear and no longer become a factor Increasing the amount of grinding aid will make the cement easier to grind Hard burning = hard grindingEverything you need to know about clinker/cement Grinding

Introduction The production of fine particles in the lower micron range by dry grinding processes demands large amounts of energy For instance, the cement industry alone consumes approximately 12–15% of the world’s total industrial energy, whereby the fine finish grinding of the cementitious products accounts for about 30% of In this study, it is aimed to give a new viewpoint of choosing utilization rates and type of grinding aids (GA), taking into account cementpolycathoxylate etherbased waterreducing admixture (PCE) compatibility For this purpose, the effects of amine and glycolbased GA utilization rate on clinker grinding efficiency and the physical Effect of amine and glycolbased grinding aids utilization rate on
