A Review on Failure Modes and Cracking Behaviors of Polypropylene Fibers Reinforced Concrete

Despite being strong under compression, concrete is rather weak when subjected to tensile stress. Concrete has been reinforced with a variety of materials over time in order resist stresses. Among various types fibers, polypropylene fiber, which available range sizes, used strengthen concrete. The fiber also increases the concrete’s toughness, durability, and low permeability. Polypropylene fibers may be utilized place conventional reinforcement, according number researchers. aim this study collect information from already carried out research on fibers. Important characteristics concrete, such as workability, compressive, tensile, flexural strength, are reviewed. review explores cracking behavior failure modes Furthermore, durability aspects, water absorption, porosity, dry shrinkage, microstructure (scan electronic microscopy), were Results indicate that improved mechanical strength (particularly capacity) but decreased flowability optimum dose important, higher adversely affects due lack flowability. Scanning microscopy results restrict propagation cracks, improves indicates shrinkage cracks considerably reduced addition Finally, provides future guidelines for upcoming generations further improve performance reinforce
