Introduction to Construction Materials - JSS2 Basic technology Lesson Note

Construction materials play a crucial role in building technology, providing the foundation and structure necessary for various architectural and engineering designs. Key materials include:

• Concrete: A composite material composed of cement, water, and aggregates (such as sand and gravel), known for its durability and ability to withstand compression forces. It is versatile and commonly used in foundations, walls, and structural elements.
• Steel: Renowned for its strength, ductility, and resistance to tension forces. Steel is used in structural frameworks, reinforcement bars in concrete, and roofing materials due to its high strength-to-weight ratio and flexibility in design.
• Timber: Natural wood that offers aesthetic appeal, thermal insulation, and sustainability. It is used in structural framing, flooring, and decorative elements, providing warmth and texture to buildings.
