Concrete using recycled aggregate trialled in Berlin
During the construction of a new building at Humboldt University in Berlin (Germany), a new form of concrete produced from sustainable resources and which uses recycled aggregate instead of gravel was employed for the first time. This has been permitted under current regulations since 2004, but has been rarely explored in construction due to lack of demand.
The pilot project was initiated by Berlin’s Senate Department for Urban Development and Environment, with the technical support of Cottbus-Senftenberg University of Technology. In the first phase of construction, walls were built using around one third of recycled concrete. A local company took up the challenge to develop the composition for this new type of concrete while another developed a process for the preparation of the recycled concrete material.
Michael Müller, Senator for Urban Development and Environment, said that the aim of the pilot project was to test the applicability of the material and process to future projects, not only in the construction of buildings but also for road construction and civil engineering.
