Sekundärrohstoffe (Recycling-Baustoffe, RC-Baustoffe) finden bereits Anwendung als Roh- bzw. Brennstoffe in der Portlandzementklinkerherstellung, als Zementbestandteile, als Betonzusatzstoffe sowie als sekundäre Gesteinskörnungen in Beton. In einem Teilprojekt des DAfStb/BMBF-Verbundforschungsvorhabens 'Nachhaltig Bauen mit Beton' wurde das Einsatzpotenzial von Sekundärrohstoffen in Beton untersucht. Hierbei spielen sowohl technische als auch ökologische und ökonomische Fragestellungen eine wichtige Rolle. Vor diesem Hintergrund wurde eine Bewertungsgrundlage mit ganzheitlicher Betrachtung von Nachhaltigkeitsaspekten (Technik, Ökologie, Ökonomie) ausgearbeitet. Dieses Bewertungskonzept umfasst die vier Bewertungsschritte: I. Grundsätzliche Überlegungen, II. Vorteile für das nachhaltige Bauen, III. Alternative Bewertungswege und IV. Sensitivitätsanalysen. Das Bewertungskonzept wurde am Beispiel der bereits im Betonbau eingesetzten rezyklierten Gesteinskörnungen entwickelt.---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Nowadays there are several applications of secondary mineral materials and residues. In the framework of the German research project 'Sustainable Building with Concrete', a concept to assess the applicability of already used and new secondary materials in concrete has been developed. It considers sustainability aspects and includes the following four assessment steps: I. Basic considerations, II. Advantages for sustainable construction, III. Alternative paths of application, and IV. Sensitivity analysis. Depending on changing technical, ecological and economic aspects, the assessment has to be performed for changed technical, ecological and economic conditions as necessity arises.

T1 - Assessment concept for the sustainable use of secondary aggregates in concrete T2 - International conference on advances in construction materials through science and engineering (RILEM Proceedings) N2 - Nowadays there are several applications of mineral recycling materials and residues. At present an assessment method for the use of secondary raw materials, which considers sustainability aspects, does not exist. In the framework of the German DAfStb/BMBF research project 'Sustainable Building with Concrete' an assessment concept was developed. It includes the following four assessment steps: I. Basic considerations, II. Advantages for sustainable construction, III. Alternative paths for application, and IV. Sensitivity analysis. The concept was developed on the basis of recycled concrete aggregates, which are already used according to German standards. Afterwards, it was applied and verified by the evaluation of the utilisation of municipal solid waste incinerator bottom ashes.

Because of highly sophisticated reprocessing techniques residues with relatively stable composition over a certain range and relatively defined properties can be produced. At the same time, new German and European regulations demand a waste management to decrease waste volume stored at landfills to save natural resources and to enhance sustainable development by recycling of diverse residues. This paper shows the activities of the working group 'Saving Resources by Material Recycling'.
