Experimental Investigations on Mechanical Properties and Fire Resistance of Steel-Polypropylene Hybrid Fiber Reinforced Concrete

Abstract:

This paper investigates the mechanical properties and the fire resistance of steel-polypropylene hybrid fiber-reinforced concrete. The type of the polypropylene fibers are polypropylene monofilament fiber, polypropylene fibrillated fiber, and macro polypropylene fiber, and the type of the steel fibers is hooked steel fiber. The experimental results show that the compressive strength, splitting tensile strength and flexural properties of steel-macro polypropylene hybrid fiber reinforced concrete are better than any others. And the fire resistance of steel-monofilament polypropylene hybrid fiber reinforced concrete is the best.
