Recycled concrete aggregates

The subject of concrete recycling is regarded as very important in the general attempt for sustainable development in our times. In a parallel manner, it is directly connected with (a) increase of demolition structures past out of performance time, (b) demand for new structures and (c) results--especially in Greece--of destruction by natural phenomena (earthquakes, etc.). The present paper refers to the concrete recycling subject and, more specifically, to a proposal for Greek specifications of recycled concrete aggregates (RCA) with reference to international experience and practice. The existence of Greek specifications of RCA--the European ones will come much later--will help Olympic Games 2004 to be as “green” as possible.
