摘 要:将一定比例的粉煤灰同石灰、石膏等材料混合,在一定条件下处理即得到预处理粉煤灰;将它同水泥熟料及石膏按适当的比例磨细,则可得到预处理粉煤灰水泥、这种水泥克服了普通粉煤灰水泥早期强度低的缺点,并增加了粉煤灰的掺量,为粉煤灰在水泥行业的大量利用开辟了新途径。Pretreated fly ash can be obtained wben fly ash is blended with lime gypsum, etc. in a certain proportion and treated under a certain coudition. Pretreated fly-ash cement can be obtained when this pretreated fly ash is ground with clinkers and gypsum in a proper proportion. This cement overcomes the shortcoming of the low early strength of ordinary fly-ash cement and the fly-ash amount adding to the cement is increased, thus a new way is opened up for the utilization of fly ash in large quantities in the cement industry
