| Abstract | Durch die Verwendung von Abbruchmaterial in Form von Beton- oder Mauerwerksbruch als Gesteinskornung im Beton lassen sich zum einen enorme Mengen des anfallenden Bauschutts wiederverwenden, sodass eine Entsorgung fur diese Stoffstrome nicht erforderlich ist. Zum anderen lassen sich Primarrohstoffe fur die Herstellung von Betonbauteilen einsparen, wodurch der weltweiten Verknappung von Sand und Kies effektiv entgegengewirkt wird. In den letzten Jahren wurden die (verfahrens-)technischen Methoden zur Aufbereitung solcher Abbruchmaterialien stetig weiterentwickelt und das Angebot an rezyklierter Gesteinskornung ist noch lange nicht erschopft. In Deutschland werden durch normative Regelungen die Anwendungsbereiche von ressourcenschonendem Beton (R-Beton) festgelegt und die Rezyklatmengen in Abhangigkeit von der Expositionsklasse auf maximal 45 % der groben Gesteinskornung begrenzt. Mithilfe dieser Studie wird das Verformungsverhalten von R-Betonen mit 100 % Rezyklat naher charakterisiert. Deformation properties of concrete containing 100 % recycled aggregateThrough the use of demolition material in the form of broken concrete or masonry as aggregate in the concrete, enormous amounts of the construction waste can be reused, so that a disposal of these material flows is not necessary. On the other hand, primary raw materials for the production of concrete components can be saved, which effectively counteracts the global shortage of sand and gravel. The procedural technical methods for the processing of such demolition materials have been continually developed in recent years and the range of recycled aggregate is far from exhausted. In Germany, the application areas of recycled concrete are defined acc. to normative regulations and the recyclate quantities are limited to a maximum of 45 % of the coarse aggregate depending on the exposure class. With the help of this study, the deformation behavior of R-concretes with 100 % recycled aggregate will be characterized more detailed. |
