🔍 Day 2 of the CONTRABASS Week – 3rd Workshop Highlights!

Today, we had the incredible opportunity to visit the carbonation reactor at Heidelberg Materials’ cement plant in Górażdże, Poland 🏭🇵🇱

It was fascinating to learn about the design and construction process of the reactor and how it operates. A huge thank you to Maciej Zajac for giving us this unique chance to explore the cement production process from the inside—a truly eye-opening experience that brought research closer to real-world application for our DCs! 🙌

📢 Afternoon Session – Industrial Talks on Cement & Concrete Recycling
Our workshop continued with valuable insights from our industrial partners:
🔹 Maciej Zajac (Heidelberg Materials):
“Engineered Carbonation in Cement and Concrete: First Industrial Experience”
🔹 Bruno Huet (Holcim):
“Optimization of Semi-Dry Carbonation of Recycled Concrete Aggregate: Experimental and Modeling Approaches”
🔹 Claire Giraudeau (CHRYSO):
“The Influence of Using Concrete Fines in Paste on Mortar Rheology”

Thank you to all speakers for your engaging talks and discussions, and to our DCs for raising thought-provoking questions! 💡🎤

📚 Now we’re ready to dive into the 3rd Training School with sessions on project management, IP, and more in the coming days!
