Effect of Polypropylene Fiber on compressive Strength of Self Compacting Concrete

Self-compacting concrete has improved quality and improved performance and performance due to its high capacity and elimination of collisions. Self-compacting concrete is designed for structures with complex reinforcement and without vibration. Does a good job of covering the ground.Fiber contribution in self-compacting concrete is 1.2%, 1.8% and 2.2%. In cases where fly ash remained unchanged, comparative studies were conducted on the compressive strength of self-compacting concrete with different polypropylene fiber contents. 25% fly ash is also used instead of cement. Extensive benefits of self-compacting concrete (SCC) in full fill the mold and achieving full compaction without vibration, with good behavior after concrete cracking, raise the idea of self-compacting concrete production. The fundamental challenge in this area is the unsatisfactory performance of concrete with fibers; In other words, using fibers in concrete will reduce concrete fluidity. In this research paper polypropelenfiber is used to improve the compressive strength of self compacting concrete.
