ABSTRACT
Slurry infiltrated fibrous concrete [SIFCON] is a recent form of superior performance fiber reinforced concrete made by penetrating steel fiber bed, with an exceptionally designed cement-based slurry. Researches have demonstrated that SIFCON is an imaginative building material, having both extensive ductility and high strength. In the current investigation, the use of SIFCON has been investigated as a strengthening layer for conventional concrete section. The effects of the SIFCON layer position: bottom, top & bottom, and jacket, thickness: 15 mm, 25 mm, and 35 mm, and steel fiber volume fraction: 6.0%, 7.5%, and 9.0% on ultimate flexural load, toughness, and ductility of hybrid prisms were reported. The results showed that the increase in the thickness of the SIFCON layer and the steel fiber volume fraction improve load-bearing capacity,
toughness, and ductility of the composite sections. The ultimate flexural load was improved by up to 1148%. Ductility factors were increasing up to 2.54. On the other hand, toughness enhanced greatly in the case of the top and bottom hybrid sections. It was 33 times higher than of control prisms.
