INCORPORATION OF DISCARDED FOUNDRY SAND INTO CONCRETE BLOCKS

Abstract

Industrial growth and society's current demand for industrialized products generate many consequences, as through the processes required to manufacture parts, various wastes are generated, including a type of solid waste that is generated by the foundry industries, which is discarded foundry sand. Currently, efforts are being made to provide a final destination for the waste generated, as there are no suitable facilities for this purpose, which leads to undue deposition of sand. In this case, an experimental study was carried out to verify the feasibility of using discarded IMF foundry sand. The entire process from natural sand to final residue (ADF) was monitored. An analysis of the sand was carried out taking into account the requirements determined by technical standards, such as compressive strength and water absorption. After the testing stage, the results were analyzed and the feasibility of using sand incorporated into concrete blocks was verified.
