A judicious use of natural resources, achieved by the use of by-products and waste materials, and a lower environmental impact, achieved through reduced carbon dioxide emission and reduced natural aggregate extraction from quarries, represent two main actions that meet sustainable construction development. Recycled-aggregate concrete containing high-volume fly ash is an example of construction material in harmony with this concept, whereby sustainable construction development is feasible with satisfactory performance, in terms of both safety and serviceability of structures, at lower costs and with environmental advantages over ordinary concrete. In this paper, criteria are discussed on the basis of which recycled-aggregate concrete mixture proportions can be optimized as well as the fresh concrete behaviour during placing. Moreover, when using recycled aggregates appropriately, some important properties of the hardened concrete such as ductility and durability can be better engineered, as this paper emphasizes.
