The test includes flexural strength and compressive strength of concrete. The compressive strength test of concrete was conducted in which the cubes of size 150mmx150mmx150mm were cast and their strength was tested at age of 7days and 28 days each. The percentage replacements were (0%, 0.5%, 1.5%, 2.5%). It was seen that compressive strength increased in each case as compared to conventional concrete. It was observed that the compressive strength at 28 days increased at 0.5% addition of coconut fibers about 1.8% of the normal hardened concrete and at 1.5% addition it was about 6% of the normal concrete. At 2.5%, the value of compressive strength was ultimate among all the percentages of coconut fibers and at this percentage the strength value was about 8.5%. Also beams having size 500mmx100mmx100mm were cast to test the flexural strength of concrete at 7days and 28 days. Replacement percentages were same as that of the compressive strength i.e (0%, 0.5%, 1.5%, 2.5%). In flexural strength test, the value of flexural strength at 0.5% addition of coconut fibers increased by 1.5% of ordinary concrete. At 1.5%, the flexural strength was increased by 4.5% of normal concrete and the maximum strength was observed at 2.5% addition of these fibers and it was about 9.5 % after 28days of curing. So almost 48 samples were casted and for both 7days and 28days testing. The design mix used in this research was M20 and all material properties were tested and the results obtained are all mentioned in this report. Hence, the results showed that the strength of concrete improved with the increase in proportion of coconut coir fibres. The maximum strength obtained for a mix is with the proportion of 2.5% addition of coconut fibres. The use of these coir fibers reduces the environmental effects, produces economically and eco-friendly concrete.
