are also used as grinding aids. Currently, triethanolamine, was the most commonly used grinding aid in cement industry but with a high cost. Moreover, it seems not as effective as expected for some mineral admixture such as blast-furnace slag and steel slag which have higher hardness than clinker. Therefore, designing a cost

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 beha-ves differently. An addition of 0.02 % of TEA to Portland cement, acts as a set accelerator, at 0.25 % it acts as

the industrial grinding of cement, even without the use of grinding aids. Therefore it can be assumed that the surfaces of the majority of commercial clinkers are predominantly or even completely hy - droxylated. This is also important because it as-sists the grinding, in other words water is a weak grinding aid. The chemical reaction of oxide ions

A method for directly measuring content of triethanolamine in a cement grinding aid by an improved liquid chromatographic method is provided. According to the improved method, a micellar aqueous solution of a surfactant is used as a mobile phase, and on a common reversed-phase column, content of triethanolamine in a cement grinding aid is directly analyzed by high pressure liquid chromatography.
