摘要
用ＸＲＤ对ＡＬＣ废渣中添加氢氧化钙后的ＡＬＣ－ＣＨ系统，在室温至１０００℃范围内加热过程中的物理化学变化进行了跟踪测定。β－Ｃ２Ｓ在７００～８５０℃开始形成，在８５０～１０００℃大量形成。并对掺加有１０００℃下的ＡＬＣ－ＣＨ烧成物的水泥进行了强度测定。表明，可以用添加氢氧化钙后再加热的方法使ＡＬＣ废渣活化。与ＡＬＣ原渣相比，用活化ＡＬＣ渣掺入水泥中，水泥的强度降低幅度显著减小。
The physicochemical changes of ALC CH system during heating between 100 to 1000℃ were traced by means of XRD analysis. The strength development of the cement mortar added with raw ALC waste or activated ALC waste at 1000℃ was followed by mortar test. β C 2S was found beginning to form between 700℃ and 850℃,and continuing to form on a large scale between 850℃ and 1000℃. The mortar test results showed that the reduction rate of strength of the cement added with activated ALC waste was compensated to some extent as compared with that of raw ALC waste, indicating the possibility of using the ALC waste in large amounts in cement.
