摘　　要：废弃混凝土的再利用已成为建筑节能降耗的主要途径之一。为提高再生骨料性能而采用的强化处理技术,将产生更多的细粉。介绍了通过将该细粉磨细后,进行X衍射分析和对混凝土性能影响的对比试验。证明该种再生磨细掺合料是具有一定活性,并完全可用于实际工程。因此,再生磨细掺合料的生产,既解决了骨料强化处理后产生细粉的处理问题,又开发出废弃混凝土再利用的新产品。Recycling waste concrete has been one of main approach of the energy conservation in construction consumption-reducing.In order to improve recycled aggregates properties, applying strengthening treatment technique produces more micronization.The XRD Analysis of milled micronization and experimental comparison on effect of properties of concrete is introduced,which proves that recycled mill admitxture living can apply to practice.Production of recycled mill admitxture solves the problem of micronization after strengthening treatment and exploit new prod- ucts by recycling waste concrete.
