PROBLEM TO BE SOLVED: To provide a method rapidly producing calcium aluminate monocarbonate excellent in grain size controllability by using inexpensive raw materials and an inexpensive device. SOLUTION: Aluminum hydroxide as one of raw materials is subjected to grinding treatment, and is mechanochemically activated, thus mutual reaction between slaked lime and calcium carbonate progresses, and calcium aluminate monocarbonate is synthesized in water at ordinary temperature under ordinary pressure. In this case, when high speed shear mixing treatment is performed at the start of the reaction, the fining and satisfactory dispersion of primary particles can be attained together with the acceleration of reaction time.
