MECHANICAL PROPERTIES OF CONCRETE WITH COARSE RECYCLED AGGREGATES

There is concern over the huge amount of construction and demolition waste (CDR) produced by the construction industry in Europe. This paper describes the recycling of CDW from the demolition of the Jose de Alvalade Stadium in Lisbon, Portugal into aggregates mainly for road pavements. The demolition process is outlined. The composition of the demolition waste was mostly concrete rubble, which was processed to produce three grades of recycled concrete aggregate (RCA). The effects of coarse RCA on the mechanical properties (compressive strength, modulus of elasticity) of concrete were studied. The flexural behaviour of reinforced concrete beams produced with RCA was examined. The higher water absorption of the RCA mortar decreased the workability of RCA concrete if the same water content was used as that for concrete made with coarse natural aggregates.
