摘要：Fiber-reinforced concrete (FRC) is concrete containing fibrous material which increases its structural integrity. It contains short discrete fibers that are uniformly distributed and randomly oriented. In addition, the character of fiber-reinforced concrete changes with varying concretes, fiber materials, geometries, distribution, orientation, and densities. Generally fibers do not increase the flexural strength of concrete, and so cannot replace moment–resisting or structural steel reinforcement. Indeed, some fibers actually reduce the strength of concrete. In this project work polyester fibers of 0.5%, 1%, 1.5% and 2% is used and its compressive, split tensile and flexural strength is determined. In this phase optimum dosage of concentration of fibers is determined. Steel slag was found to be the best replacement for natural aggregates of concrete. Steel slag which is produced as a waste material in the steel industry and has a negative impact on environment when disposed. In the course of future project work by the replacement of steel slag for the coarse aggregate in concrete of 25%, 50%, 75% & 100% with the addition of optimum polyester fibers to achieve the effective strength of concrete.
