摘要
机场道面翻修、改(扩)建工程会产生大量的废弃混凝土,如何利用废弃混凝土作为再生骨料,配制道面再生混凝土,满足机场道面工程设计与施工要求,采用掺加优质粉煤灰和高效外加剂的"双掺"技术路线,进行道面再生混凝土配合比设计。室内试验表明,所配制的道面再生混凝土性能优于普通道面混凝土,现场施工实践也表明,所配制的再生混凝土可以用于机场道面工程,是一种新型绿色环保混凝土。
The overhauling,rebuilding and enlarging of airport pavement often produced vast waste concrete.This paper aims at how to make concrete with the waste concrete which is used as recycled aggregate,also meets the design and construction requirements of airport pavement project.By adopting the ＂double mixing＂ technique with high quality fly ash and high efficiency admixture,optimizing the mix proportion design of pavement recycled concrete.The indoor testing results show the pavement recycled concrete is superior to common pavement concrete,and the field application effect shows the recycled concrete is a new kind of green,economical concrete,can be used in airport pavement construction.
