In 1996 a new law called “Kreislaufwirtschafts- und Abfallgesetz” (circulating economy and waste material law) was introduced in Germany. It specifies that the person who produces, sells, or consumes a product has to recycle or dispose of the remaining waste material in a manner that complies with relevant environment regulations. The best outlet for used building material is to produce new concrete. The findings of a research project, “Baustoffkreislauf im Massivbau” (building material cycle in structural engineering) led to preparation of new construction guidelines called, “Beton mit rezykliertem Zuschlag” (concrete with recycled concrete aggregates) published by the DAfStb (German Committee for Reinforced Concrete). This paper presents the work performed by the Technische Universitat Miinchen, which deals with the verification of the dimensioning values. Mainly creep, shrinkage and bond tests were carried out. This project is supported by the BMFT (Bundesministerium fur Forschung und Technologie, Federal Ministry for Research and Technology) and the industry and results are also published on the world wide web, at http:\\www.b-i-m.de.
