Influence of Mixing Method of Mineral Admixture on Performance of Recycled Concrete

Abstract:

In order to improve the microstructure of recycled concrete, the mineral admixtures were mixed into recycled concrete by different mixing method in this paper. It is demonstrated that the early compressive strength of recycled concrete decreased when mixed by fly ash only, but its later strength increasing rate is higher than recycled concrete without fly ash. When mixed fly ash and silica fume in the recycled concrete, the compressive strength of recycled concrete with fly ash and silica fume is higher than the strength of recycled concrete with fly ash only, and its microstructure tend to be dense.
