Aplicação dos resíduos de construção e demolição como agregado graúdo e material cimentício suplementar

Abstract

The present work deals with the generation, impacts, laws and current norms related to Construction and Demolition Waste (RCD) and Civil Construction Waste (RCC). The study presents a bibliographic survey on the reuse of these residues in the construction processes themselves, replacing the natural aggregates present in concrete and as an additional cement compound. The survey shows that substitutions are possible, provided that some points are observed, such as the water absorption capacity and the heterogeneous origin of the residues. It is also clear the need to control the management and processing of RCCs and RCDs so that they can be reincorporated in the construction processes of the construction industry.
