Aufbereitung von Teilströmen der Abfallverbrennungsasche zu hochwertigen Zuschlagstoffen und deren Einsatz als Recyclingprodukte in der Baustoffindustrie In the framework of the project OPTIMIN a fractionation of BA in different grain size distributions with an integrated washing step has been carried out. Due to further treatment and measurements of the resulting three fractions 0-0.2 mm, 0.2-2 mm and 2-25 mm, the possible application in asphalt, concrete or cement has been investigated. One option could be the use of fresh BA which has been treated prior to the ageing processes. The preliminary results show the shifting of pollutants to the fine fraction but also components responsible for the ageing processes. Parts of the fine fraction hold the limit values for the cement plant of the project partner. On the other hand, the Contents of copper and zinc exceed the standard values for the process. The coarser fractions are free from mineral coatings and are not agglomerated in the case of the use of fresh BA. A following industrial separation step of glass has been successful. From the physical point of view an application in asphalt or concrete for the coarser fractions seems to be feasible. However, in leaching experiments a high release of different metals, especially copper, could be detected. This is probably due to the poorly conceived washing process but needs to be further investigated. 1 Neuruppin TK Verlag 2018 Mineralische Nebenprodukte und Abfälle 5 978-3-944310-41-1 152 172 2018-11-19
