The fresh and hardened properties of self-compacting concrete (SCC) containing fiber was investigated in this paper. The fiber has a continuous impact on the environment that promotes expect to accept the natural fibers like the coconut fibers for strengthening the concrete. The fiber has different proportion of aspect ratio of 0.1to 0.4 in SCC was adopted. Based on the flow of SCC the naphthalene-based superplasticizer ranging from 0.8 to 1% was used. To achieve the targeted strength of M30, twelve mixes were prepared and the fresh properties like flowing, filling and passing abilities were assessed through slump flow, V-Funnel and L-Box. The results of the mechanical properties of SCC showed that the addition of coir fiber 0.1 to 0.4% in SCC containing superplasticizer has no significant development in strength still upon 0.4% replacement the strength was improved to 2% on compared with the reference concrete. Addition of the coir fibers in concrete has led to higher improvement of tensile strength.
