Abstract: The recycling of CDW is satisfying form the aspect of reused quantities but it is unsatisfying form the aspect of produced kinds, qualities and fields of application. So far only about 1% of the produced recycled aggregates is used fort he production of concrete. A progess can be achieved if the specific properties of recycled aggregates are take more in consideration. One the one hand the the standards and rules for recycled aggregates have to define the quality more exact and to connect them with the heterogeneity. On the other hand the possibilities of the processing technologies should be used more stricly fort he quality improvement. Already today by the indroduction of suitable techniques for liberation and sorting such recycled aggegates can be produced which have nearly the same properties like natural aggregates. For such aggregates no separate standards would be necessary.
