Unit 2836: Construction Materials

1. Introduction to Construction Materials

• Overview of construction materials in the industry
• Classification:
  • Natural materials: wood, stone
  • Synthetic materials: concrete, steel
  • Composite materials

2. Properties of Construction Materials

• Key properties:
  • Strength (tensile, compressive, shear)
  • Durability and weather resistance
  • Thermal conductivity and insulation
  • Sound insulation
• Impact of properties on material selection

3. Wood as a Construction Material

• Characteristics of wood
• Types of wood used in construction
• Timber framing techniques
• Engineered wood products: plywood, laminated veneer lumber (LVL), cross-laminated timber (CLT)
• Sustainability considerations and environmental impact

4. Concrete and Masonry Materials

• Composition of concrete: cement, aggregates, water, admixtures
• Types of concrete mixes and their applications
• Reinforcement methods: steel rebar, fibers
• Masonry units: bricks, blocks, stones
• Properties and typical uses in construction

5. Steel and Metal Alloys in Construction

• Structural steel: grades, forms, and standards
