Experimental Investigation on Properties Concrete Paver Block with the Inclusion of Natural Fibers

In this experimental investigation the compressive strength, water absorption and flexural strength of paver blocks were determined by adding Coconut fibers in the top 20mm thickness. Coconut fibers were added in proportions of 0.1%, 0.2%, 0.3%, 0.4% and 0.5% in volume of concrete. The compressive strength, flexural strength and water absorption were determined at the end of 7 and 28 days. Test results indicate that addition of coconut fiber by 0.3% paver block attains maximum compressive strength. Test results indicate that addition of coconut fiber gradually increases flexural strengths and water absorption at 7 and 28 days. In this investigation at 0.3% of coconut fiber content effect of top layer thickness on compressive strength and flexural strength is also determined. Results show that inclusion of fibers even up to 50% of top layer thickness compressive and flexural strengths are increasing. The paper also shows the cost comparison per each block.
