| Abstract: | To improve the mechanical properties and crack resistance of recycled concrete,this paper have a research on recycled concrete with polypropylene fiber and steel fibre and analyse the strength,brittleness,the proportion of tensile strength and compressive strength. Results show that adding hybrid fiber can improve compressive strength and splitting tensile strength and the anti-cracking performance of recycled concrete and can reduce the brittleness of recycled concrete. |
