【摘要】 本文研究以 Na₂SiO₃为激发剂的粉煤灰渣-碱胶结料（简称 FKJ）的反应机理和水化产物.分析认为 FKJ 系统中可能生成的主要水化产物为方沸石型的水化硅铝酸钠.其次为钙沸石型的水化硅铝酸钙和杆沸石型的水化硅铝酸钠钙.还有少量的低碱度水化硅铝酸钙。FKJ 胶结料有良好的抗碳化性、抗冻性、耐化学侵蚀性等.故具有广阔的应用前景。更多还原

【Abstract】 In this paper,the study of the reactive mechanism and hydrate products of the fly ash slag—alkali cementitious material（namely FKJ）,Which Na₂SiO₃ is taken as an activator is stressed.By the analyses,we consider that,in the FKJ system,the main hydrate products possibly produced are sodium—sillicoaluminate hydrate of analcite type.The secondary prod- ucts are calcium-silicoaluminate hydrate of scolecite type and sodium-calcium-silicoaluminate hydrate of thomsonite type,meanwhile a small amount of low-alkaline calcium silicate hy- drate are also produced. In the paper,the properties as to good durability,fine carbonation resistance,frost re- sistance and resistance to chemical attack etc of the FKJ binder are also expounded.There- fore it is possessed of bright prospect in application.更多还原
