EXPERIMENTAL STUDY ON MECHANICAL PROPERTIES OF CONCRETE USING RECRON 3S FIBER

Concrete is a versatile engineering material used in most civil engineering structures, so great attention is required to improve the concrete property by improving its strength and durability. In the current scenario, Recron-3s, which is a polypropylene monofilament short fiber strings that can be used in concrete are used to control and stop cracks. In this study, an attempt has been made to study the different mechanical properties of concrete consisting of Recron 3S fibers. The proportions of the mixture were casted with M40 and M45 grade concrete. For strength parameters compressive strength, split tensile strength and flexural strength were performed on hardened concrete of M40 grade and M50 grade with combination of Recron 3S fiber of varying percentages i.e. 0%, 0.25%, 0.50%, 0.75% to that of cement weight at the age of 28 days and the test results were compared. It is observed that the concrete combined with Recron 3s fiber have the maximum compressive strength, split tensile strength and flexural strength when Recron3s fiber content is 0.25% after 28 days curing.
