Experimental Study of Splitting Tensile for Multi-Scale Polypropylene Fiber Concrete

Abstract:

Through splitting tensile tests on 30 plain concrete and polypropylene fiber concrete specimens with the dimensions of 100mm × 100mm × 100mm , studied the influence of the different scales of polypropylene fiber and hybrid fiber on concrete splitting tensile strength and splitting tensile deformation. The results showed that: the splitting tensile strength of concrete for single-doped fine fiber had increased 7%~31%,for single-doped coarse fiber had increased 7%~39%,and mixing-doped coarse-fine fiber had increased 2%~50%. Doped-fiber can improve the concrete splitting tensile toughness, it's enhancement sort: mixing-doped coarse-fine fiber concrete > single-doped coarse fiber concrete > single-doped fine fiber concrete> plain concrete
