中文摘要：

将含钛高炉重渣与Ca（OH）2以9：1的质量比混合，添加15％、2 mol／L的NaOH溶液，利用水热固化技术，低温（200℃）制备出抗折强度约15MPa的建筑材料焉；果表明，成型压力、固化温度、固化时间等因素对固化体强度的形成均有重要影响。水热过程中，生成的CSH和水化石榴石晶相是导致固化体强度提高的重要原因。水热固化技术为含钛高炉重渣的大规模综合利用提供了新的途径。

英文摘要：

Building material with tensile strength of around 15 MPa was prepared by mixing titanium-containing blast furnace slag（TBFS） and Ca（OH）2 in mass ratio of 9：1,adding 15% 2mol/L NaOH solution with the help of the hydrothermal solidification under lower temperature of 200 ℃.The results showed that compaction pressure,curing temperature and curing time had important influence to the formation of the strength of solidified bodies.In the hydrothermal process,the generated calcium silicate hydrates （CSH） and hydrogarnet are the important factors improving the strength of the solidified bodies.The hydrothermal solidification method may provide a new approach for recycling use of TBFS slag on a large scale.
