Concrete Science Research Brief: Clinker: When Impurities Matter

March 1, 2011

This research highlights the critical role of guest ions on available reactive sites in alite and belite. The novel understanding of the role of impurities on reactivity opens the possibility for designing new doped clinker phases with a higher reaction rate, and hence, earlier strength development. Engineering the reactivity of belitic cements could thus become a reality through an appropriate choice of impurities. MORE
