Abstract
Self-compacting concrete which has excellent deformability in the fresh state and high resistance to segregation it can flow under its own weight and does not need any vibration. In recent years, Self-Compacting Concrete (SCC) has gained a vital use for placement in congested reinforced concrete structures with difficult casting condition. For such application, the fresh concrete must possess more fluidity and high cohesiveness. The uses of fine materials in self-compacting concrete are needed such as fly ash can ensure the required concrete properties. It had an excellent strength property not only that, it reduces the requirements of cement. And addition of fiber to self-compacting concrete (SCC) especially steel fibre improves its structural properties. Current study has been made on fly ash, with various percentage of mixes were prepared with fly ash ranging from 5% to 15% and steel fibre added for each percentage of fly ash as 1%, 1.5% and 2% in self-compacting concrete to improve the strength properties for M60 grade of concrete.
