【摘要】 本文采用测定水化过程结合水量、XRD和 SEM等技术研究了纯高钙粉煤灰的水化及S—激发剂对高钙粉煤灰的激发作用。结果表明 ,高钙粉煤灰由于含有较多的 f Ca O,水化时产生较大的膨胀而使试样粉化、无一点强度 ,掺入 S—激发剂可较好地激发高钙粉煤灰的潜在水硬性 ,增加水化过程结合水量 ,从而使掺有 S—激发剂的高钙粉煤灰试样水化不同龄期后均有一定的强度更多还原

【Abstract】 Using XRD,SEM and testing the amount of bound water during the process of hydration, we study the hydration of high Calcium fly ash and the accelerative function of S-accelerator on high Calcium fly ash. Results show, because of there are quite more f-CaO in high Calcium fly ash, the samples smashed after hydration, have no strength. After adding S-activitor,it promoted the potential harden activity of high Calcium fly ash, the amount of bound water also increased, it led the samples of high Calcium fly ash have strength after different hydration days.更多还原
