Effect of transitional aluminas on Portland cement hydration, phase assemblage and the correlation to ASR preventing effectiveness

This study reveals the impact of transitional aluminas on the hydration kinetics, phase assemblage of Portland cement, and ASR preventing effectiveness. Transitional aluminas were obtained by annealing reactive alumina mainly consisting of γ-Al2O3 at various temperatures. Their impacts on hydration...
