摘要
Graphene oxide has many advantages, such as high strength, high electricity, heat conductivity and so on. It can be used in cementitious composite material to strengthen the strength and improve durability. In order to study the effect of graphene oxide on recycled concrete, the mechanical properties and frost resistance of recycled concrete with graphene oxide contents of 0%, 0.02%, 0.04% and 0.06% were studied. The results show that with the increase of graphene oxide content, mechanical properties and frost resistance of recycled concrete are improved obviously. At the same time, in order to study the modification mechanism of recycled concrete with graphene oxide, the microstructure of recycled mortar was observed by scanning electron microscope. The results show that the microstructure of recycled mortar is improved after adding 0.06% graphite oxide. © 2016, Editorial Office of Journal of Building Structures. All right reserved.
