【Abstract】 The hydrated calcium aluminate was synthesized by hydrothermal treatment at normal pressure,and then it was burned at low temperature to prepare calcium aluminate cements(CAC s).By XRD,DTA and the examination of the strength of CAC s,the mechanism of CACs burned at low temperatuere was also studied.It is indicated that the activity and strength of CACs pretreated by hydrothermal synthesis low temperature burning are higher than those of conventional sintered products,and the method of hydrothermal synthesis low temperature burning can be used instead of the conventional method to produce CACs.更多还原
