Comparative long-term measurements on buildings made of normal concrete and concrete made of reprocessed aggregate

The amount of building rubble in Germany is steadily increasing. And this is a high-grade raw material, which it is possible to reuse as an aggregate for making concrete.

The amount of building rubble in Germany is steadily increasing. And this is a high-grade raw material, which it is possible to reuse as an aggregate for making concrete. In the course of a building project sponsored by the Federal Ministry of Eduction, Science, Research and Technology (BMBF) and the industry, two structurally identical buildings were built from conventional concrete and from recycling concrete. The article describes the design and implementation of a measuring device which makes it possible to furnish evidence about the long-term behavior of both buildings.
