Entulhos de Obras de Construção Civil

The paper aims to present the strategies for innovation in construction and demolition waste management in Brazil and to compare them with international ones. The CDW traditional management is very costly to local authorities including several environmental impacts. The Brazilian experience shows that a policy based only on regulation of …

This article aims to apply the combination of heavy media and hand sorting in representative samples of Brazilian CDW aggregates from two different recycling plants and to characterize relevant fractions by chemical, mineralogical and physical tests. Three national CDW coarse recycled aggregates were sampled, sieved, separated in four heavy media …

Os objetivos deste artigo são diagnosticar aplicações potenciais do RCD com enfoque na diversificação de mercados para a reciclagem massiva e avaliar as necessidades para a reciclagem em larga escala de RCD em agregados para concretos. Como conclusões, o uso de agregados de RCD reciclados em bases de pavimentos não …

O objetivo desta comunicação técnica é apresentar as razões e estratégias para o aperfeiçoamento do processo de reciclagem da fração mineral do RCD com o objetivo de produzir agregados reciclados com qualidade controlada para uso em concretos. Estas estratégias serão adotadas em um projeto de pesquisa envolvendo o Centro de …

Three representative samples of construction and demolition waste recycled as aggregates were taken from two different Brazilian recycling plants. The samples were fractioned by sink-and-float and sieving techniques. The chemical composition, the main mineralogical phases and physical characteristics such as bulk specific gravity of these fractions were determined. The applied …
