COMPARATIVE STUDY OF EFFECT OF BASALT, GLASS AND STEEL FIBER ON COMPRESSIVE AND FLEXURAL STRENGTH OF CONCRETE

This paper presents the comparative study of effect basalt, glass and steel fiber on compressive and flexural strength of M40 grade concrete. For flexural and compressive strengthening of reinforced concrete, total thirty-nine cubes and thirty-nine beams were cast and beams were tested over an effective span of 900 mm up to failure of the beam under two-point loading. The beams were designed as balance-section. The fibers were placed in concrete randomly by (0.25%, 0.5%, 0.75%, 1%) of its total volume of concrete. For each percentage of fiber total three cubes and three beams were casted to take average results. Finally comparative results are shown for each percentage and for these three fibers
