In this study, the effects of alkanolamine on the hydration reaction of calcium aluminoferrite with different compositions were examined under various conditions in which calcium hydroxide and calcium carbonate coexist. As a result, alkanolamine promoted the hydration reaction of calcium aluminoferrite, and the reaction-promoting effect was especially pronounced in ferrites with high Fe2O3 ratios. Among alkanolamines, triethanolamine, which had a remarkable effect of increasing the degree of Fe and Al elution, was confirmed to accelerate the reaction rate of calcium aluminoferrite in particular. The reaction acceleration of alkanolamine was similarly confirmed in the system with calcium hydroxide and calcium carbonate.
