Splitting Tensile Strength of Steel Fiber Reinforced Concrete Cylinders Consolidated by Rodding or Vibrating

Abstract

The relative strength of rodded and externally vibrated steel fiber reinforced concrete cylinders are compared for both standard compression and split-cylinder tension tests. Fiber concentrations ranged from 0 to 8 percent by weight of concrete. Test results of this pilot program indicate that external vibration increased the split-cylinder tensile strength by as much as 20% over that of standard rodded cylinders. The tests also provided some data on the effect the addition of steel fibers has on the split-cylinder tensile and compressive strength of concrete.
