This project reports on an experimental program to investigate the effect of using steel fiber as a replacement of fine aggregate on the strength properties. Fiber reinforcement is commonly used to provide toughness and ductility to brittle cementation matrices. The study of toughness of fiber reinforced concrete (FRC) is based on different fiber proportions. The experimental investigation is carried out on fiber reinforced concrete containing different hybrid combinations of crimpled steel and hooked end fibers are reported. The physical, workability tests and mechanical properties namely compressive strength, flexural strength test, split tensile strength, compaction factor test were studied for concrete prepared by using different fiber combinations –crimpled steel (Aspect ratio 50)-hooked steel (Aspect ratio 80), crimpled steel (Aspect ratio 65), crimpled steel fibers alone, hooked end fibers alone and a plain concrete specimen. Reinforcement of concrete with a single type of fiber may improve to desired properties to a limited level.

Steel fiber (crimpled + hooked end), Fine aggregate, Partial Replacement, M30 Grade Concrete, Workability, Compressive Strength, Flexural Strength, Split tensile Strength.
