ABSTRACT

Abstract This report describes the state of recycling of reinforced concrete from buildings in Germany. Furthermore, the effect of recycling on the total cost of reinforced concrete and composite structures as well as the consumption of primary energy is investigated. Finally, the requirements for environmentally adapted construction in concrete is dis­ cussed. Keywords; Buildings, Recycling, Concrete, Rebar, Structural Steel, Primary Energy Consumption

1 Demolition Concrete for the Use in Road Construction

Since 1988 dumping costs, for building rubble have risen, with strong regional variations, from between 7 to 40 DM/t to between 80 to 200 DM/t and they still continue to rise, Willkomm, (1990). Transporting building rubble to neigh­ bouring countries which might accept the rubble and have larger dumping potential is politically and ecologically undesirable, nor is it feasible in most cases due to the transportation costs.
