摘要
在大量试验的基础上，采取常温下预处理—粉磨工艺以改善粉煤灰的性能。结果表明，用70％粉煤灰取代水泥可以制得425＃粉煤灰硅酸盐水泥，为提高粉煤灰在硅酸盐水泥中的掺量开辟了一条新的途径。
On the basis of a great many of tests, the properties of fly ash can be improved by the pretreatment such as grinding at normal temperature. The results show that 425 portland fly ash cement can be produced by replacing cement with 70% fly ash. This technology has opened up a new way for increasding the adding content of fiy ash ln portland cement.
