Chemie ist heute allgegenwärtig - auch beim Bauen und in Bauwerken. Wofür Chemie hier gut ist, zeigen eindrucksvoll die jährlichen Tagungen Bauchemie. In diesem Jahr ist diese Tagung an der Hochschule Karlsruhe - Technik und Wirtschaft zu Gast. Die Fachgruppe Bauchemie der Gesellschaft Deutscher Chemiker (GDCh) zeichnet - wie immer - für das Programm verantwortlich. Die Bedeutung dieser am 5. und 6. Oktober stattfindenden Tagung zeigt sich daran, dass der Volkswirtschaft jährlich Milliarden Kosten durch Bauschäden entstehen.
