The S6 enters the tetrahedral position replacing the Si4 ions in the belite structure and stabilizes it at high temperature. Other stabilizing ions are Fe3 and Al3 resulting the greenish yellow or pale yellow up to amber belite color..

  • Morphological Analysis of White Cement Clinker Minerals

    The paper deals with a formation of artificial rock (clinker). Temperature plays the capital role in the manufacturing process. So it is useful to analyze a poor clinker to identify the different phases and defects associated with their crystallization. X-ray fluorescence spectroscopy was used to determine the clinker #x2019s chemical composition. The amounts of the mineralogical phases are

  • Sulphure Volatility Sulpatisation Sulphure in clinker

    With increasing use of high sulphur fuels such as petcoke the "normal" SO3 content of clinker has increased substantially. In practice an SO3 content of >1.5 would only have a serious detrimental effect if the cement produced from this clinker were used in steam-cured concrete (>70oC).
