FLEXURAL AND SHEAR BEHAVIOR OF RC BEAMS REINFORCED BY POLYPROPYLENE FIBER

Fiber reinforced cementitious composite is a composite consisting of concrete/mortar as matrix and short fibers as reinforcement. The fiber resists external forces by bridging effect across cracks. Polypropylene short fiber is one of the improved polymer fibers and has already been used to prevent spalling of cover concrete, to reduce drying shrinkage strain, and to prevent explosive spalling during a fire. Because of the wide applicability, the...
