Experimental Study on The Rigid Pavement With Comparison of Polyester And Coconut Fiber As A Partial Replacement of Cement

This project work involves an experimental investigation of the artificial and natural fibers those are polyester and coconut fibers on the mechanical properties of the concrete used in the rigid pavement. In this experimental study involves two types of concrete mixes were prepared individually. Polyester fiber of 0.5% to 2.0% and coconut fiber of 0.5% to 2.5% by weight of cement were added to the mixes. After that a comparative analysis has been carried out for conventional concrete to that of the fiber reinforced in relation to their compressive, split tensile and flexural properties. In this study the observation shows that, the percentile of fiber content increases from 0%, 0.5%, 1%,1.5% for polyester fiber and 0%,0.5%,1.0%,1.5%,2.0% for coconut fiber in concrete mixes. By the experimental work the compressive, split tensile and flexural strengths are proportionally increased both polyester and coconut fiber usage. It is observed that the optimum dosages of polyester fiber is 1.5% and coconut fiber is 2.0% by weight of cement. In this project cost analysis is also determined for conventional concrete and fiber reinforced using experimental test reports. By analyzing the cost it was found that polyester reinforced concrete pavement increases to 49.77% and coconut reinforced concrete pavement decreases to 4.20% when compared to conventional concrete.
