Abstract
This paper outlines laboratory study on chloride resistance of waste plastic fibre reinforced self compacting concrete. Self compacting concrete mixes with varying percentages of waste plastic fibers like 0.0%,0.25%,0.5%,0.75%,1.00%,1.1%,1.2%,1.3% and 1.4% were developed for M40 grade of concrete. The mix proportion was done by NANSU method. The result of fresh property test satisfies the limits specified by EFNARC. The cubes and cylinders were immersed in 5% magnesium chloride solution for a period of 30 days, 60days and 90 days. The degree of chloride attack is determined by evaluating the reduction in compressive strength split tensile strength and percentage loss of weight of specimen. From the test results it is observed that maximum compressive strength and split tensile strength were achieved for 1% of plastic fibre. The chloride content is determined by Argentometric titration method. Percentage loss of weight, loss in compressive strength and chloride penetration have decreased as the percentage of fibre increased.
