Who should attend
This intensive training course is designed to those working in industry and research laboratories who would profit from a thorough presentation and discussion on the basic knowledge about geopolymers and their applications in Toxic and Radioactive Waste Management. This includes:
- Chemists
- Chemical Engineers
- Materials Scientists
- Materials Engineers
- Physico-chemical Scientists
Learning Objectives
Upon completion of this course, you will be able to:
- Describe the fundamental principles and concepts, differences prevailing between traditional Encapsulation or Vitrification methods and Waste-Geopolymerization.
- Outline the identification and the study of best geopolymeric systems for Long-Term Safe Containment.
- Identify the reaction mechanisms that provide Archaeological and Geological Long-Term Durability.
