Characterization of Brazilian construction and demolition waste coarse recycled aggregate

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 …

Applied Mineralogy characterization of construction and demolition waste from Brazilian recycling plants

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 …

Strategies for innovation in construction and demolition waste management in Brazil

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 …
