The present study investigates the effect of phosphates on hydrothermal treatment of CAC system at 60$$^{circ}$$C, 105$$^{circ}$$C and 180$$^{circ}$$C. The treatment of conventional CAC resulted in formation of stable C$$_{3}$$AH$$_{6}$$ and $$gamma$$-AlOOH. Modification by mono-phosphate appeared to have delayed the hydration and overall reaction of CAC, whereas poly-phosphate appeared to significantly stabilise the amorphous binding phase up to 180$$^{circ}$$C. No crystalline phase was observed except hydroxyapatite when poly-phosphate was used.
