Abstract
This experiment describes the behavioral study of coconut fiber in concrete structure. The addition of coconut fiber in concrete improves various properties of concrete. Addition of coconut fiber improves the Flexural strength of concrete. The experiment was conducted on high strength concrete (M60) with the addition of coconut fiber with 5 different mix proportions 1%, 2%, 3%, 4%, and 5% by the weight of cement. The Flexural strength of cured concrete evaluated for 3, 7 and 28 days. Test results indicate that addition of coconut fiber by 1% concrete attains maximum strength. Test results indicate that addition of coconut fiber gradually increases Flexural strengths for 3, 7 and 28days. This results show coconut fiber can be used in construction.
