Popis:	Hydration of the compounds of the system CaO-Al2O3 (i.e. CAn; C3A, C12A7, CA, CA2 and CA6) in phosphoric acid solutions was studied at 35°C under a saturated pressure and at 100°C and 200°C by hydro thermal techniques under the pressure of 10 MPa. At 35°C, C3A hydrated to form C3AH6 within 1 h in water, while C12A7, CA and CA2 yielded C2AH8 after 1 day, which changed gradually into C3AH6 in water.
