Construction with recycled aggregate concrete – Influence on design and construction of reinforced concrete structures. Apart from the need to reduce huge quantities of CO₂ emitted in cement production in particular, an efficient use of diminishing natural resources such as sand and gravel is indispensable for a more eco efficient concrete production. In this context, the use of recycled aggregates seems to be a promising alternative to natural aggregates in conventional concrete to save natural resources. Since 1998, the use of recycled aggregate in structural concrete is allowed in Germany following the guideline issued by the German Committee for Structural Concrete (DAfStb). With the new edition of Eurocode 2 (FprEC2), regulations for the use of recycled aggregate concrete (RAC) are also included for the first time. Starting with the properties of RAC compared to natural aggregate concrete (NAC), the current regulations for design of RAC are compared and an outlook on future research focussing not only resource efficiency but also CO₂ emission reduction in concrete production is given.
