Effect of Glass Fibers on the Mechanical Behavior as Well as Energy Absorption Capacity and Toughness Indices of Concrete Bridge Decks

In this study, the incorporation of glass fibers in concrete bridge decks has been studied for improving its mechanical properties as well energy absorption capacity and toughness indices. The mix proportion 1:3:2 (cement:sand:aggregate) was selected having water-cement ratio 0.71. For manufacturing fiber reinforced (GFRC), (2-inch) were incorporated at a percentage level 1 %, 2 3 % 4 by weight cement mixes. findings reveal that split-tensile flexural strength GFRC increases all levels, however, compressive blended mixes get reduced increasing dosage concrete. Besides, indices are also different types loadings (i.e. compressive, splitting-tensile loadings) up to %. increased with increase comparison conventional mixes, Whereas, spilt-tensile flexure while compared Among percentages fibers, addition gives better results Hence, GF can be suggested optimum mix-design controlling resistance decks. Although, is lesser indices, appropriate enhancing ductility against
