Abstract
In this study, the scope of research will be focused on the flexural fatigue behaviour of steel fiber reinforced concrete. The fatigue life data of SCFRC containing 0.5 %, 1.0 % and 1.5 % by volume of steel fibres have been obtained by conducting flexural fatigue tests on approximately prism specimens of size 100 x 100 x 500 mm under third point loading at stress level 0.70. In present investigation is mainly focused on the effect of steel fibers on mechanical and flexural fatigue properties on M30 concrete.Pavement concrete is mostly used for airfield runways, road surfaces, bridge decks, parking lots and industry floors. Due to passing vehicles, these structures often endure repetitive cyclic loads during their service lives, the fatigue characteristics of concrete in these structures are important performance and design parameters. It is necessary to predict the fatigue life and parameters for structures that have been endured repeated loading. Fatigue failure occurs when a concrete structure fails at less than design load after being exposed to a large number of stress cycles. Fatigue may be defined as a process of progressive and permanent internal damage in a material subjected to repeated loading
