IMPACT RESISTANCE OF CONCRETE CONTAINING BOTH CONVENTIONAL STEEL REINFORCEMENT AND FIBRILLATED POLYPROPYLENE FIBERS

Concrete beams containing both conventional steel reinforcing bars and different volumes of fibrillated polypropylene fibers were tested in an instrumented, drop-weight impact machine. Imapct strength and fracture energy were determined. The presence of fibers led to a considerable increase in fracture energy; the peak bending loads were not affected. The increase in fracture energy was much greater than the sum of the effects of polypropylene fibers and reinforcing bars considered separately.
