Abstract As one of the primary hydrated products of cement, monosulfoaluminate (AFm) could realize chloride binding via exchanging ions between interlayer sulfate ions and chloride ions, which played a crucial role in enhancing the chloride binding capacity of cementitious materials and reducing the corrosion risk of reinforcing concrete. To enhance the chloride binding capacity of AFm, barium ion with different concentrations was introduced into chloride salt solutions immersing AFm, the chloride binding capacity of AFm sample at each age was compared. The phase compositions, thermal properties and microscopic morphology of AFm sample at each age were analyzed, and the change rule of barium ion concentration in the solution at each age was analyzed. The effect of barium ion with different concentrations on chloride binding of AFm was discussed, and the mechanisms behind were investigated. The results indicate that barium ion can consume sulfate ions of AFm to promote the ion exchange reaction between AFm and chloride ions and enhance the chloride binding capacity of AFm. But the mechanism of AFm on chloride binding is different with different concentrations of barium ions. Barium ion with low concentration promotes the formation of AFt and Friedel's salt, while ba-rium ion with high concentration generates more Kuzel's salt.

Key words： monosulfoaluminate barium ion chloride binding barite Friedel's salt Kuzel's salt
