活性煤矸石粉在注浆材料中的应用

Application of Active Gangue Powder as Grouting Material

由于煤矸石活性差、单独与水反应慢,仅有较弱的胶凝作用,因此采用了多种活性激发复合措施充分激活煤矸石潜在的火山灰反应活性,并探讨了经活化处理过的煤矸石粉在注浆材料中的应用。研究表明,煤矸石经活化处理后,活性有显著的提高,以其作为主要原材料所研制的注浆材料早期强度高,性能优越,符合现行注浆材料检验标准,从而实现了工业废渣大掺量的“资源化”利用,具有良好的社会效益和环境效益。

Because of coal gangue has lower activity,reaction with water is very slow and its gelatinization is also minor,therefore several stimulative activity methods are used to stimulate intensivelythe potential pozzolanic reaction activity of the gangue. The results show that the activity of gangue after activation is improved obviously,the early strength of the grouting material is increased and other mechanical properties are superior also, which accord with the grouting materials test standard adopted at present.
