Ganzheitliche Eignungsbewertung von Sekundärrohstoffen für den Einsatz in Beton

Holistic concept to assess the applicability of secondary materials in concrete

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.
