摘要
通过对比煤矸石磨细灰与粉煤灰性能,明确煤矸石磨细灰的主要特征,对其进行混凝土性能试验,结果表明,在混凝土中用一定量煤矸石磨细灰取替水泥,取代率在15%左右时,混凝土各项性能与纯水泥混凝土几乎一致。
By comparing the performance of coal gangue grinding fine ash and fly ash,the main characteristics of fine ash are clarified.The concrete performance test is carried out and the results show that when the rate of replacement of cement by fine ash is about 15%,the concrete performance is almost the same as that of pure cement concrete.
