Fiber reinforced concrete (FRC) is being widely used as the structural material owing to its superior engineering properties. From the past, it was understood that Fiber Reinforced Concrete had been proved to be well performing over the time under different practical situations. Fibers enhance the mechanical properties of concrete and in turn change the structbehaviouravior. It is observed that high strength fibers are available such as steel fibers, carbon fibers, basalt fibers, glass fibers etc. Large number of literatures are available to study the influence of these fibers on the flexural behavior of conventional concrete. Application of finite element analysis (FEA) in the behaviour of structural members is gaining momentum. The results from Finite Element Analysis need to be validated with the IS code provisions. In the present research work, an attempt was made to understand the effect of fiber in the deflection of Prestressed concrete beams both through Finite Element Analysis and Indian and American Codes.

“…Natomiast beton z włóknami przenosi obciążenie, nawet po osiągnięciu ugięcia, które powoduje pękanie betonu zwykłego. W przypadku włókien o dużej wytrzymałości, do których należą węglowe, bazaltowe i szklane, dostępna jest bogata literatura (2). Dostępne są jednak tylko ograniczone publikacje na temat stosowania włókien bazaltowych, w formie mono-i hybrydowej.…”

Addition of fiber is a promising solution, to enhance the flexural behaviour of reinforced cement concrete [RCC] beams. It improves the peak load, ductility and energy absorption characteristics of RCC. Ineffective mono fibers in the concrete perform very effective, when combined through the hybridization and contribute towards the strength. Fiber hybridization offers appreciable improvement in fresh and hardened properties of concrete. To achieve optimum performance, synergetic effect of fibers is more important. Incorporation of two fibers in concrete matrix, bridges the cracks effectively. Hence to investigate the effect fiber hybridization in the flexural performance, RCC beams were cast, experimented and the results were compared with the control beams. In the present study, it is intended to evaluate and compare the impact of steel and basalt fibers in mono form and hybrid form, on the flexural parameters such as first crack load, load response behaviour, ductility, crack width and flexural strength of RCC beams. To evaluate the mechanical properties of M40 grade fiber reinforced concrete, volume fractions chosen were 0.25%, 0.5% and 0.75%. Comparatively addition of basalt fibers with steel fibers, improves synergetic response to a considerable extent. From overall assessment of the mechanical properties, it was established that the combination of basalt and steel fibers at 0.25% and 0.75% respectively, produced optimum results. Optimum volume fraction of fibers identified is used in the casting of RCC beams. Wherever possible, flexural parameters were cross checked, with Indian Standards.
