The hydrothermal hot-pressing method is a very useful technique for solidifying various inorganic materials. The authors have tried to apply some cementitious materials to this process. A commercially available alumina cement is used and the effects of addition of sodium phosphate and silica fume are examined to increase the strength of solidified alumina cement. The reaction temperature is 250 °C, and the reaction time is 60 min. The maximum tensile strength of the solidified bodies reached at about 24 MPa when alumina cement is replaced by 2.5 mass% of silica fume and modified with 10 mass% of sodium metaphosphate.
