Hypothesis
The study aims to evaluate the potential of Al-containing industrial residues as secondary raw materials in construction to support the EU Green Deal and circular economy.
Conclusion
The study found that fly ash is the most suitable material for use in the cement industry, while other residues like red mud and slags have limited viability for metal recovery.
Supporting Evidence
- Fly ash has favorable radiological and mineralogical properties for use in cement.
- Red mud and other residues have limited potential for metal recovery.
- The study supports the EU Green Deal by promoting the use of secondary raw materials.
- Characterization of residues provides a foundation for future innovations in construction materials.
- Secondary raw materials can help reduce CO2 emissions in the cement industry.
Takeaway
This study looks at different types of industrial waste and how they can be reused in building materials, which helps the environment by reducing waste.
Methodology
The study involved collecting and analyzing 19 samples of industrial residues for their physical, chemical, mineralogical, and radiological properties.
Limitations
The study primarily focuses on the characterization of residues without extensive exploration of their practical applications in construction.
