materials for construction

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
