Abstract:In order to study the concrete rib-typed permanent template, reinforced concrete specimens with different fiber contents were designed and manufactured, the experiments for compression, bending (folding) and impact resistance were carried out. The toughness of different fiber concrete was tested by compression-bending ratio, bending and impact resistance performance experiments. The results show that the toughness of steel fiber reinforced concrete is higher than that of PVA fiber concrete, and the toughness of long fiber concrete is higher than that of short fiber concrete.

Keywords:fiber concrete; concrete rib typed permanent template; toughness test
