Leibniz-IWT live: The recyclable material aerated concrete - proposal for a recycling strategy
Event details
The year starts with a new "Leibniz-IWT live" topic under the sign of sustainability: aerated concrete. On February 16, Dipl.-Ing. Frank Hlawatsch (MPA) will present different recycling methods for crushed aerated concrete within the online format of Leibniz-IWT.
The building material aerated concrete (AAC) has enjoyed great popularity in Germany since the 1960s, as insulating monolithic wall constructions can be erected from the specifically lightweight mineral building material without the need for additional insulation measures. The advantageous properties of autoclaved aerated concrete as a primary building material, such as low bulk density and good thermal insulation, cause problems as a recycled material in the construction waste stream: low grain strength, high water absorption capacity, lack of frost resistance. Up to now, aerated concrete has usually been landfilled.
The Leibniz-IWT live lecture on February 16 will present different recycling routes for crushed aerated concrete developed at Leibniz-IWT, MPA Bremen business unit, with the support of the Forschungsvereinigung Recycling und Wertstoffverwertung im Bauwesen e.V. (RWB): Methanox functional layer for landfill construction, factory dry mortar, lightweight stone, foam stone.
The registration for the amount of Dipl.-Ing. Frank Hlawatsch is possible here.
