An Experimental Study on Human Hair Fiber Reinforced Concrete

Abstract

Fibers have the property to enhance the toughness of concrete. The cost of construction has skyrocketed together with the deteriorative impact on setting. This resulted in the adoption of a more balanced approach with the environment as its nerve centre to create a better world to live in. This has led to the adoption of a fiber like Coconut for the strength sweetening in concrete. Coconut fiber is obtainable in abundance, which makes it quite viable as a reinforcement material in concrete. This paper presents a experimental discussion on the subject of coconut fiber-reinforced concrete, CFRC. It discusses usually used terms and models of behavior that kind a basis for understanding material performance with presenting mathematical details. In this research it is shown that flexural strength of coconut fiber reinforced concrete is directly proportional to the coconut fiber content and inversely proportional to the water-cement ratio. This study aimed toward analyzing the variation in strength of coconut fiber concrete at variable fiber contents and to establish it with that of conventional concrete. The various strength aspects analyzed are the flexural, compressive and lastingness of the coconut fiber concrete at variable percentages (1%, 2%, 3%, 4%, 5%) by the load of cement of fiber. Result data clearly shows percentage increase in compressive strength for M20 grade of concrete in 7 days and 28 days with respect to the variation in % addition of coconut fibers. This research is based on the use of coconut fibers in structural concrete to enhance the mechanical properties of concrete.
