“…The serviceability aspect should also be taken into account, especially when analyzing structural members where long‐term deflections are detrimental in design. In Reference 40, RC slabs representing a typical floor structure of a residential building and made either of NAC or RAC with 100% replacement of natural coarse aggregate were compared. Both slabs were designed to fulfill the same functional requirements: strength, long‐term deflections, service life of 50 years (for XC3 exposure class according to Eurocode 2), and fire resistance.…”

The environmental impacts of activities such as raw material extraction, construction of infrastructure, and demolition, place construction as one of the sectors that exert the highest pressures on the environment, society, and economy. Some of the major environmental impacts for which the construction industry is responsible are mineral resource depletion, greenhouse gas emissions, and waste generation. Among the different strategies that exist to decrease such impacts, recycling demolition waste into recycled concrete aggregates has been considered a promising alternative. As such, at present, the literature dealing with the impact assessment of recycled aggregate concrete structures is very extensive. Therefore, the objective of this article is to present a critical view of the state-of-the-art in terms of sustainability assessment of recycled aggregate concrete structures, taking a holistic perspective by considering environmental, social, and economic impacts.

“…The concrete is recovered in two types of aggregates. Recycled aggregates (RA) are composed of several materials in significant proportions and represents most of the recovered flow, and recycled concrete aggregates (RCA) are mainly made of concrete waste Marinković and Carević (2019). The RA and RCA replace natural aggregated (NA) to produce recycled aggregated concrete (RAC).…”

Neben der drastischen Reduktion von CO2‐Emissionen bei der Zementherstellung ist ein effizienter Umgang mit knapper werdenden natürlichen Ressourcen wie Sand und Kies unumgänglich, um die Betonindustrie umweltfreundlicher zu gestalten. In diesem Zusammenhang erscheint die Verwendung rezyklierter Gesteinskörnung als sinnvolle Alternative zu natürlicher Gesteinskörnung in herkömmlichem Beton. Seit 1998 ist der Einsatz rezyklierter Gesteinskörnung in Konstruktionsbeton in Deutschland nach der Richtlinie des Deutschen Ausschusses für Stahlbeton (DAfStb) möglich. In der Neuauflage des Eurocode 2 (FprEC2) werden erstmals Regelungen für die Verwendung von Beton mit rezyklierter Gesteinskörnung (R‐Beton) aufgenommen. In diesem Beitrag wird zunächst auf die Eigenschaften von R‐Beton im Vergleich zu Beton mit natürlicher Gesteinskörnung eingegangen. Anschließend werden die aktuellen Regelungen zur Bemessung einander gegenübergestellt und ein Ausblick auf zukünftige Forschung gegeben, die nicht nur den Ressourcenschutz, sondern auch die wirksame Reduktion der CO2‐Emissionen in der Betonproduktion im Fokus hat.
