The Circular Economy, CE, is becoming more and more important, although the reasons are many. These include economic change, disruptions in supply chains, shrinking natural resources and environmental protection. Polymers in concrete, C-PC, are a fairly recent phenomenon in the centuries-old history of concrete. C-PC as new technology was the leitmotiv of the first ICPIC Congress, which was held almost 50 years ago. And now the time has come to search for a new paradigm in this field.

During this Special Symposium, you will have the opportunity to listen to some inspiring lectures, as well as take part in a general discussion on finding new solutions for C-PC in the circular economy.

Special Symposium entitled “C-PC in Circular Economy: Searching for a New Paradigm” is an integral part of the 17th ICPIC Conference and will take place on September 18, 2023. We encourage all interested parties to participate in the conference and symposium.
