Essential Construction Materials: Concrete, Wood, Metal, Masonry & Glass

1. Construction Materials Mr. O’Rourke Construction

2. Five Main Categories • Concrete • Wood • Metal • Masonry • Glass

3. Concrete • Used in almost every type of construction • One of the most important STRENGTH

4. Concrete Ingredients • Cement Paste- Made of Portland cement and water • Aggregate- Fine sand mixed with stones • Chemical reaction between water and cement hardens (sets the concrete)

5. Concrete Properties • Strong- Reinforced with rebar • Watertight • Workable

6. Working with Concrete • Preparing-Forms are prepared • Placing-Pouring near its final location • Finishing-Using a straightedge to level off • Curing-Done in moist conditions

7. Wood Materials Lumber: • Boards-sheathing, siding, paneling • Dimension Stock-Form wood frame of house • Timber- Posts and beams

8. Other Wood Materials • Plywood- subfloors, roof decks • Laminated Timbers- Lumber that is glued together (arches, poles and beams) • Oriented Strand Board- Chipboard • Pressure Treated Wood- Chemicals forced into wood to preserve

9. Metal Materials • Steel- Used for framing • Aluminum- Siding, roofing • Copper- Plumbing pipes and roofing

10. Masonry Materials • Clay Masonry- Consists of brick and tile • Concrete Masonry- Brick and Block form

11. Building Masonry Projects • Laying out- Laying out materials in planned positions- Then space and cut • Laying up corners- Build corners (leads) • Laying between corners-Filling in walls between corners • Tooling-Compacting and shaping the mortar

12. Glass All glass buildings, doors, windows, etc. • Flat glass-Clear, tinted, or opaque • Tempered glass- Heat treated • Insulated glass- Two layers of glass with dry air in between
