Abstract

In order to reduce the influence of freezing-thawing cycle on the recycled concrete and improve the use of recycled concrete in cold regions, this paper systematically explored the influence of different variables such as the mix ratio of recycled aggregate, the content of basalt fiber and freezing-thawing cycle on the mechanical properties of recycled concrete. The results show that adding basalt wire can improve the bearing capacity and ductility of the recycled concrete, but the mechanical properties of the recycled concrete are greatly reduced after the freeze-thaw cycle.
