| 摘 要： | 通过试验研究了混凝土中粉煤灰对引气剂所引含气量的影响,试验结果表明:混凝土中掺入劣质粉煤灰,混凝土拌合物含气量会随粉煤灰掺量的增加而降低,掺优质粉煤灰较不掺加时混凝土拌合物含气量稍有降低,但不会随粉煤灰掺量的增加而降低。

| Abstract: | Experiments are carried out to study the effects of fly ash on air content in the concrete mixture induced byair-entraining agent. Results show that when mixed with low-quality fly ash, air content in the concrete mixture will be decreased with increasing the dosage of fly ash. While compared with that without fly ash, the air content in concrete mixed with high quality fly ash would be slightly lower, but it will not decrease with the increase of the dosage of fly ash. |
