Concrete is the most versatile man-made construction material in the world and being extensively used in all types of construction activities. The strength, durability and other characteristics of concrete depend upon the properties of its ingredients, the mix proportions, the method of compaction and other controls during placing, compaction and curing. To enhance these properties, an attempt was made to study the durability property by introducing polypropylene fibers in concrete. In this paper effect of polypropylene fibers on the durability of concrete for M30 grade have been studied by varying percentage of polypropylene fibers in concrete. Fiber dosages of 0.5%, 1%, and 1.5% by volume of concrete were used in the experimental study. Concrete cubes of size 150mmX150mmX 150mm were tested for compressive strength, Resistance to Acid Attack for 28 days, 56 days curing period. Polypropylene fibers were randomly dispersed in concrete. The results indicated that increasing the volume fraction of fiber showed decrease in compressive strength after subjected to acid attack. High volume PFRC was shown to be more vulnerable to acid attack.
