Recycled Aggregates

This chapter introduces the reader to the basic characteristics of construction and demolition waste (CDW) as well as recycled aggregate, which is one of the most important products obtained from construction and demolition waste. Composition of CDW, including its most interesting component (concrete), as well its management is discussed. Valorization plants (stationary and mobile) for the treatment of construction and demolition waste are explained. Recycled aggregates, reprocessed materials previously used in construction, are further discussed and their main properties commented. Finally, the applications of recycled aggregates are briefly commented: production of concrete and pavements as well as general fill and embankment material, and for erosion control.
