The Scale Circular content can be studied sequentially or accessed directly by topic across the main modules:

• Structure of Materials: atomic structure, chemical bonds, and materials classification by nature
• Cement: EU Current Cements, manufacturing process, hydration reactions and kinetics, microstructure development, hardened state cement paste
• Mortars and Concrete: composition, production, and fresh and hardened state properties
• Microstructure-Property Relationships: connecting internal structure to chemical, physical, and mechanical properties, including durability
• Sustainability and Circular Economy: secondary raw materials, supplementary cementitious materials, and the role of the cement-based materials in circular construction.

A visually rich Glossary is available throughout the app.

Quizzes allow for topic-based knowledge testing and will progressively adapt to each user’s learning profile and knowledge.
