Adjusting LC³ Cement Composition
This lecture covers the impact of sulphates in LC³ cement, the role of sulphates in Portland cement, the importance of sulphation in cements with calcined clays, and the effects of alumina content and alkalis on early strength and reactivity. It also discusses the alkali silica reaction, the use of alumina silicate supplementary cementitious materials to prevent ASR, and the influence of kaolinite content on alumina reserves. The presentation concludes with a summary emphasizing the need for sulfate level adjustments and proper alkalis balance in LC³ systems to enhance reactivity and control ASR effectively.
