EFFECT OF USING RECYCLED AGGREGATES ALONG WITH FIBRES AS A REINFORCEMENT ON THE MECHANICAL PROPERTIES OF CONCRETE

The increase in urbanization has lead to increase in the infrastructural needs ultimately leading to the depletion of natural resources, therefore the research community has focused on utilization of alternate construction material. The use of recycled aggregates from construction and demolition wastes is one among which is showing prospective application in constructions alternative to primary (natural) aggregates. On the other hand Fiber Reinforced Concrete (FRC) is one of the fastest growing segments in the concrete industry to supply their reinforcing needs in concrete applications. Even though lot of research has been done in their respective areas, but seldom can be found on their combination. In our research, we have laid emphasis on different percentage replacements of natural aggregates with recycled aggregates in fibre reinforced concrete. The effect on compressive and flexural strength by replacing natural aggregates with recycled aggregates at different proportions of polypropylene fibres was evaluated.
