Comparative Characterization of Clinker’s Microstructure at Different Temperature Zone during Cement Production

Abstract

Temperature is an important parameter for transformation of minerals in clinker during cement productions. It influences the formation of alite from belite during calcinations and clinkering processes. The result of microstructure shows that the formation of belite minerals started at temperature nearly 1200°C which is at calcinations zone temperature, followed by formation of ß-belite at higher temperature (around 1300°C), then formation of ß-belite and finally, with the suitable conditions it will form alite minerals. The differences between minerals are identified physically using scanning electron microscope (SEM).
