Investigation on the effect of using banana fiber in normal C-25 Grade concrete

Civil Engineering

Concrete is relatively brittle, and its tensile strength is typically only about one tenths of its compressive strength. Regular concrete is therefore normally reinforced with steel reinforcing bars but due high cost of steel bars Fibers used in concrete production. A Fiber is a small piece of reinforcing material possessing certain characteristics properties. Addition of fibers to concrete influences its mechanical properties which significantly depend on the type and percentage of fiber. The property of fiber reinforced concrete is influenced mainly by the physical and mechanical properties of the fiber. The objective of this study was to evaluate the workability, unit weight, compressive strength of concrete and tensile strength after 7th and 28th days curing. The study considered 0%, 0.5%, 1%, 1.5% and 2% Banana fiber in concrete production for and determination its effect on fresh and hardened concrete. Mechanical properties of waste banana fibered concrete, compression and flexural strength test with different percentage of BF range from 0 to 2% showed a good result. Increase for 0.5, 1 and 1.5% and then again decrease at 2% usage of fiber. Workability of the fresh mix decreased from its control mix due to addition of banana fiber in concrete production. Incorporation of BF in concrete was decreased the compressive strength of sample. But, the impact of 0.5% of BF compressive strength is not more significant that the result is not far more from strength of concrete control.
