“…Regarding the deviation from the mean that the most reliable was the 30% because it has a standard deviation less, the greater was the 25%, proving to be the worst, both in the measure itself and in the average resistance to comprehension. This work collaborates with researches and uses sand casting in other civil construction artifacts [10,11,12]. For we have the immediate need to remove these residues from the environment in order to have a better performance of the mechanical metal industries and a better use of the materials removed from nature.…”

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%.

“…Porém, é o material mais utilizado por apresentar um melhor benefício econômico. Ao mesmo tempo que fornece uma produção de qualidade, ao ser utilizada repetidas vezes ela deve ser substituída, acumulando uma enorme quantidade de resíduos que são descartados em aterros industriais, prejudicando o meio ambiente (COUTINHO NETO, 2004).…”

Foundry is an agile process in obtaining finished metal parts, where for each ton of sand that enters the process, an equivalent amount of waste is generated. And plastic is a widely used polymer due to its low cost and diverse application in all sectors of society, however, it has an insufficient recycling system. In this context, through this work, technical tests were carried out with artisanal production and empirical dosages, aiming at the use of these two residues, plastic and foundry sand, as raw material for an alternative material for use in masonry. The result obtained was satisfactory where all the test specimens exceeded the resistance of 6 MPa with regard to the axial compression tests, presenting itself as a possible option for the reuse of these residues.

“…Existem trabalhos desenvolvidos no Brasil com o propósito de se reutilizar a areia de fundição na construção de rodovias. Bonet (2002) propôs o reaproveitamento da areia de fundição residual como agregado fino no Concreto Betuminoso Usinado a Quente (CBUQ) e Coutinho (2004) estudou a possibilidade de utilizá-la em misturas asfálticas densas; o primeiro trabalho recomendou a utilização de 8% do resíduo na mistura asfáltica, enquanto Coutinho (2004) concluiu que até 15% de incorporação da areia na mistura asfáltica produz materiais com boas propriedades mecânicas sem impactos ambientais significativos.…”
