Concrete, one of the most universally accepted construction material, exhibits higher values of compressive strength, but the same cannot be said in terms of its tensile strength. This is the prime explanation for the setback of this construction material, to be used in place of achieving a higher tensile strength. Different endeavors have been made to improve the overall tensile strength of concrete by using diverse materials. These materials were used either as a form of replacement of its main constituents, or simply as an addition to the other constituents. Out of all such materials, the use of different types of fibers, added a definite proportion of tensile strength without actually altering the configuration of the concrete blocks to a larger extent. Also, in some cases the density of the concrete is a one of the influencing parameters in structural elements and this study is based on the optimization of fibers as a replacement of the Ordinary Portland cement (OPC) along with the use of different industrial waste by products i.e., mineral admixtures and also the light weight aggregates in order to reduce the self weight of the concrete. In this study, an attempt will be made to investigate the mechanical properties of M60 grade high strength fiber reinforced light weight aggregate concrete.
