Abstract

The research under taken at the Concrete Technology Unit (CTU), University of Dundee to create a sound technical base aimed at assisting the construction industry in using its waste as a valuable resource in concrete and concrete products is discussed. The properties of construction and demolition (C&D) waste which is ideally suited for reuse applications are also discussed. The properties of recycled concrete aggregate (RCA), comprising >95% crushed concrete, and recycled aggregate (RA), referring to aggregate containing < 95% crushed concrete are presented. It is found that a 30% replacement of natural aggregate with coarse RCA for all concrete classes in terms of engineering performance and durability.
