摘要
就粉煤灰机械化学活化前后的表观特征、需水量比、粉煤灰水泥胶砂强度作了对比研究 .结果表明 :粉煤灰活化效果明显 ,活化粉煤灰水泥胶砂 3 d强度比活化前提高 10 .7% ,2 8d强度提高 15 .5 % .
The appearance property and the rate of water needed of fly ash,and the fly ash cement mortar strength were studied when the raw fly ash and the activated fly ash were activated in machinery and chemistry process.The tests show that activation effect is distinct,and that activated fly ash cement mortar strength is more 10.7% than raw ash one in 3 days,more 15.5% than raw ash one in 28 days.The activated fly ash can be used as cement blend.
