This document discusses five main categories of construction materials: concrete, wood, metal, masonry, and glass. It provides details on the composition, properties, and uses of concrete, wood, and metal materials. Concrete is strong and waterproof when cured. Wood is used for framing, sheathing, and beams. Common metal materials are steel, aluminum, and copper. Masonry includes brick, block and clay products. Glass is used for windows, doors and all-glass buildings.

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
