Abstract

Hydration of C₁₂A₇ with or without phosphoric acid and the change for phase condition of the hardened paste in water and simulated body fluid (SBF) were studied. The hydration of C₁₂A₇ was delayed by increase in the concentration of phosphoric acid. The concentration of Al in the soaking solution increases with the soaking duration. The dissolution of Ca and Al delayed when the paste contained phosphoric acid or the soaking solution was SBF. The surface of the hardened C₁₂A₇ paste covered crystalline HAp, after soaking SBF for 7days at 37°C.
