摘要
研究了水泥掺量对流态粉煤灰流动性及力学性能的影响。结果表明,在同样的水灰比条件下,流态粉煤灰的流动性随水泥掺量增加而降低;流态粉煤灰强度随水泥掺量的增加而增加。在水泥掺量<6.00%的情况下,流态粉煤灰强度随着龄期发展增长并不明显,>6.00%时,流态粉煤灰强度随着龄期发展快速增加。
The influence of cement content on fluidity and mechanical property of flowable fly ash was studied. The results indicate that the fluidity of flowable fly ash decreased as the cement content increased under the same water/cement ratio; its strength rose with the increase of cement content. With the growth of age, the strength of flowable fly ash increased unobviously while the cement content was less 6%, but increased rapidly while the cement content was above 6%.
