Sustainable Concrete by Using Waste Foundry Sand and Carbon Fibre

The generation of solid waste i.e. used foundry sand (UFS) from the metal casting industries is growing continuously at disturbing quantity. In this study, an attempt is made to replace the fine aggregates by 30% using used foundry sand in the concrete. In addition to this carbon fiber added 0.25%, 0.50%, 0.75% and 1.00% to the volume of results indicate that the concrete of used foundry sand with 0.5% carbon fiber performance better than conventional sand concrete. Based on the test results, it is endorsed that UFS and carbon fiber can be used effectively in the manufacture of concrete without affecting the strength properties of concrete.
