Modulus of Rupture of Fully and Partially Reinforced Concrete Beams With Polypropylene Fibers


Abstract: -In this research an experimental study was conducted to explore some mechanical properties such as compressive strength and splitting tensile strength and modulus of elasticity of concrete mix with weighted mixed portions (1 : 1.5 : 2 / 0.35) reinforced with polypropylene fibers by (0.25%, 0.50%, 0.75%, 1.0%, 1.25%) as volume percentage comparing with normal concrete. Research also contain testing modulus of rupture and maximum deflection of polypropylene concrete beams with dimensions (100×100×500) mm with the same volume percentage and concrete beams with half depth fibrous concrete and the other half normal concrete and comparing with the modulus of rupture and maximum deflection of normal concrete beams.Keywords: Compressive and Tensile strength, Deflection in beams, Modulus of elasticity, Modulus of rupture, Polypropylene fiber.
