This paper deals with the effects of the mix proportions and curing conditions on the flexural strengths of MDF cements before and after water immersion are discussed to find out the effective processing techniques for improving their water resistance. As a result, the hydrolysis of a water-solu-ble polymer and the accelerated hydration of ordinary portland cement during autoclave cure are most effective to improve the water resistance of MDF cements. The optimum autoclave curing condition for improving the water resistance is a heating under a pressure of 0.98 MPa at a temperature of 180°C for 7 hours.
