There were many researches to improve the concrete quality whether physical or mechanical properties. One of the technological advances in improving the quality of concrete was by using additives. Additive was the substance that was added into fresh concrete in small quantities to improve its properties. This research was carried out to establish the effects of coconut fibre on workability and flexural strength. The mixes were prepared with fibre-cement ratio of 2%, 3% and 4% coconut fibre and control specimen. The result of adding coconut fibre will be compared with the control specimen and supported journal. There were three tests for workability; slump test, compacting factor test and Vebe test. For the flexural test, there were twenty four beam specimens with dimension 750mm length, 150mm width and 150mm thickness were test for flexural behavior. There are six beam specimens for control, six beam specimens for 2% fibre, six beam specimens for 3% fibre and six beam specimens for 4% fibre. The specimens were tested at 28 days after curing in water tank. The tested was conducted by applying load until the beam failed. The workability test results shown the workability of concrete decrease with the increase of fibre added. The result test for 28 days curing for flexural strength shown the strength was not achieved the control strength.
