This paper presents the fresh state and mechanical properties of self-compacting concrete (SCC) with addition of coir fiber (CF) as filler in range of 0.2% to 0.6% and replacing the cement in 10% with palm oil fuel ash (POFA). The workability test such as slump flow and J-ring test were used on the fresh SCC-POFA-CF mixture. The mechanical properties of SCC- POFA-CF in form of compressive, tensile and flexural strength were determine using the compressive test on cube, split tensile test on cylinder and four-point bending test on prism respectively. The increasing amount of CF in mixture resulting the decreasing of workability of SCC-POFA-CF. The SCC mixture with 0.2% CF was selected as optimum as the strength reached the allowable limit of strength. The less crack was occurred on SCC-POFA-CF compared to the control specimen. Therefore, the propagation of crack in prism of SCC was control by coir fiber.
