The Effect of Type of Fiber in Density and Splitting Tensile Strength of SIFCON

SIFCON is characterized as a construction material of high ductility and very strength. It suitable for concrete structures used special applications. However, the density much higher than that Fiber Reinforced Concrete (FRC) due to need large amount high-density steel fibers. This work examines split tensile behavior modified weight slurry infiltrated fiber utilizing mixture two types fibers, fiber, polyolefin fiber. For investigation, 30 cylinders 15 cubes were poured. The volume fraction (V.F) (6 %) use five series once each type separately hybrid in proportions 2/3 with 1/3 vice versa. splitting strength unit resulting from tests studied. results indicate produced hook-end fibers achieved good reducing while maintaining significantly decreased by 140 kg per cubic meter improved 494%.
