Abstract
This study intended to manufacture high quality cement, such as solving the quality problem of cement which has been emerging recently, along with improving grinding efficiency. To this end, the synthesis of melamine-functional pulverizing agents and the physical properties of cement applying them were reviewed and the reaction was carried out by dividing the melamine airborne compound into three stages of polymerization using methylation, sulfonation, and acid catalyst to improve the crushing efficiency of cement clinker and the physical properties of manufactured cement. The obtained melamine type copolymer was applied to the grinding process of cement clinker. And it's grinding efficiency and compressive strength were compared with DEG(diethylene glycol) and TIPA(triisopropanol amine). When it comes to the grinding efficiency, by lowering surface energy with stable adsorption from organic polymer to cement particles, the fineness showed 4-6% up. In the meantime, the compression strength hiked 30% from its initial strength compared to the conventional DEG. At the age of 28days, the strength showed approximately 13% improvement. Therefore, it is confirmed that the overall quality has been elevated in comparison with the conventional one.
