Resumo: | Currently, the use of waste in construction has been stimulated, since this sector presents as one of the largest consumers of natural materials in its processes and products. The objective of this work is to evaluate the addition of corn cob residue to the concrete production. By enabling them to become a great help in the production of lower cost alternative materials, replacing in part the natural aggregates normally used in the manufacture of concrete artifacts. The maize residues, specifically the cob, were transferred by a rural producer from Lavras, Minas Gerais, were crushed, sifted according to the granulometry of the sand, and replaced in the concrete. The trait used was obtained together with a resistance table, undergoing some modifications. At the same time, batches of batches and batches were made with replacement of the small aggregate. This work evaluated the physical and mechanical behavior of concrete with the addition of corn cob residues in the proportion of 3% of the sand mass, compared to conventional concrete. The replacement of the small aggregate by the recycled kid aggregate obtained a reduction in the results of average resistance, therefore, it does not de-characterize the potential of the corn cob residue as an alternative raw material for use in non-structural concretes. |
