Abstract


For this study, natural waste fiber (coir and jute) were used as they are freely available in large quantities. The property of natural waste fiber (coir and jute) reinforced concrete was compared with conventional concrete based on experiments performed in the laboratory. The use of coir and jute fiber will also lead to better management of these natural waste fibers. Coconut and jute fibers were cut into desire length of 71.67 mm and 96.48 mm per aspect ratio of 75. 1:2:4 ratios concrete mix was produced which contains coir and jute fiber of 0.5, 1 and 1.5% by volume of concrete. Engineering properties such as workability, flexural strength and compressive strength of coir and jute fibers reinforce concrete specimens were determined following standard procedures at curing ages of 7, 14 and 28 days. The results showed that the workability decrease from increase of fibers, while the compressive strength increased up to 4.5% and flexural strength increased up to 5.9% but dropped afterwards when compared with conventional concrete.
