ESTUDO DA VIABILIDADE DO AGREGADO GRAÚDO RECICLADO DE RESÍDUOS DE CONSTRUÇÃO CIVIL E DEMOLIÇÃO NA UTILIZAÇÃO DE CONCRETOS NÃO ESTRUTURAIS

Abstract

It is notorious, at the present time, the problem of scarcity in the deposits of materials used in the civil construction leading to studies and research on new sources and resources of materials that can be substitutes. Among these materials are the construction waste, which can be recycled and used as aggregates. The use of this recycled aggregate, besides serving as a substitute for materials, also softens the sanitation problem regarding the disposal and volume of these wastes in the environment after disposal. Therefore, this work had the objective of verifying the viability of the recycled aggregate of construction and demolition waste, by means of a theoretical and experimental study evaluating its application in the construction of non - structural concrete. Through standardized tests it was possible to make a comparison of the characteristics and properties of the recycled aggregate and the conventional aggregate. Subsequently, an analysis was performed on the experimental dosages of concrete using the recycled aggregate, alternating the type of aggregate and the type of Portland cement. With the results obtained it was possible to find a more cost-effective concrete dosage for implantation in non-structural concretes.
