摘要
研究优质 级粉煤灰对碱骨料反应的抑制效果 ,结果表明 ,用粉煤灰抑制碱骨料反应 ,其掺量因素的影响大于品质因素的影响 ;探讨了粉煤灰中的碱在不同浓度碱溶液中的溶出情况及用高碱含量粉煤灰抑制碱骨料反应时 ,低掺量促进膨胀 。
Controlling AAR with high quality I grade fly ash has been researched. The result shows that the content is more important than the quality for the effect on controlling AAR. The solubility of the fly ash contained alkali is inquired in differ alkali concentration solution. The mechanism of low [WT6,6”BZ]content accelerating swell and yet high content controlling swell is discussed when controlling AAR with the fly ash contained high alkali content.
