An Experimental Study on M-35 Grade of Concrete with Partial Replacement of Cement with Coconut Fiber

M-35 Grade, Coconut Fiber

The addition of coconut fibers in concrete improve various properties of concrete mix such as toughness, flexural strength, tensile strength and impact strength as well as mode of failure. The purpose of using coconut fiber is it tends to bind the concrete mix together, slows the settlement of coarse aggregate and reduces the bleeding which means a slower rate of drying thus less shrinkage. In hardened concrete, coconut fibers act crack arresters like any other secondary reinforcement, the fiber stop cracks from propagating by holding the concrete together so cracks cannot spread wider or grow longer. However, since coconut fibers are distributed throughout the concrete, they are effective close to where cracks start at the aggregate paste interface.The proportion of coconut fibre are varied in the percentage of 0%, 0.5%, 1.0%, 1.5% and 2.0%
