Waste and Discharge Sand Use of Foundry for the Manufacture of Concrete Tiles

The progress in the world industrial sector, together with new technologies increases solid waste generation and the consequent concern with the correct management of them. One of the biggest problems in the foundry sector is the generation of solid waste, consisting mainly of waste sands or discarded sand castings (ADF). Proper waste disposal is a challenge for industries, which are increasingly concerned about the need to preserve the environment and seeking for sustainable development. In Brazil, fused production in 2008 exceeded three million tons, generating approximately one ton of waste for each ton of metal produced. The main destination of this waste is industrial disposal landfills, which have high cost and is an increasing environmental concern for companies. Therefore, the aim of this research was to solve this problem, that is, it was proposed a methodology to reuse these solid wastes, testing our methodology by using concrete slabs with incorporation of foundry sand in different concentrations, in an increasing order of 5%, where natural sand was replaced by founding sand. The viability for the use of casting sand in relation to the resistance was significant in the traces 30% and 35%.
