Recycled Aggregates in Concrete - a Realist's Perspective

摘要

There has been much recent discussion about the use of recycled aggregates for new concrete, and a considerable amount of research has been and is being undertaken to produce technical guidance. As the technical aspects of using recycled aggregates in concrete are now reasonably well understood, I will concentrate in this article on the practical, economic and political aspects of their use. It is my opinion that the technical problems can be overcome. However, the economic and practical aspects of using recycled aggregates are potentially much more difficult to deal with, and will be far more important for their eventual use than the purely technical aspects.
