| 摘 要： | 研究了不同球磨时间的粉煤灰对水泥胶砂性能的影响,结果表明:粉煤灰经过球磨后,细度增加,活性提高。在水泥中添加经过球磨的粉煤灰可以增加水泥的强度,并且安定性合格。当粉煤灰球磨时间在20 min,掺加量在20%~30%时能够显著提高水泥的强度。

| Abstract: | This paper researched the influence of fly ash with different ball milling time to cement mortar performance, the results showed that, after ball milling, the fineness of fly ash increased, activity increased. Add the fly ash after ball milling in cement could increase the strength of cement, and the soundness qualified, when the ball milling time of fly ash was 20 minutes, adding amount in 20%- 30% could significantly im- prove the cement strength. |
