| description | This paper analyzes the basic mechanical properties of recycled concrete by changing themixing ratio of waste polypropylene fiber and basalt fiber. The results show that the compressivestrength of recycled concrete decreases in varying degrees with the addition of hybrid fibers, butthe tensile strength of recycled concrete is obviously improved with the low addition of wastepolypropylene fibers. Compared with the reference concrete group, with the change of mixing ratioof hybrid fiber, the elastic modulus of all test groups decreases in varying degrees, except thetest group whose ratio of basalt fibers to waste polypropylene fibers is 4 ∶1, and the toughness ofconcrete is greatly improved by the addition of hybrid fibers. |
