| 摘 要： | 针对我国高寒地区机场道面混凝土抗冻融性能不良的现象,结合某机场工程,对掺粉煤灰机场道面混凝土进行冻融试验,探讨了水胶比、粉煤灰掺量、引气减水剂掺量对粉煤灰混凝土抗冻融耐久性的影响。结果表明,随着粉煤灰及引气减水剂掺量的增加,机场混凝土道面的抗冻融性能会相应地提高。可对高寒地区机场水泥混凝土道面设计、维护及剩余寿命预测等问题提供参考。

| Abstract: | In view of the bad durability phenomenon of airport pavement concrete in cold region of our country, based on an airport project, experimental studies on the feezing and thawing durability of runway pavement concrete mixed with fly ash. The effects of water- cement ratio ,fly ash amount ratio and fly air-entraining agent of concrete were investigated. With the fly ash and content increased, the freeze-thaw resistance has been improved, which is essential to design, maintenance and predict the remaining life of cement concrete of airport pavement. |
