Study Notes
Masonry Tools and Materials
- A sled runner jointer is used to create long horizontal joints in masonry work.
Building Material Symbols
- Symbols on construction plans represent building materials.
- Rubble, dimension lumber, steel, and plaster are some of the represented materials, each with its distinct graphical symbol.
Mortar Requirements
- For a 200 sq ft brick wall with 3/8" mortar joints and 655 non-modular bricks per 100 sq ft, 11.6 cubic feet of mortar are needed.
Brick Types for Specific Conditions
- SW type brick is suitable for areas exposed to ground water and freezing conditions.
Modular Brick Dimensions
- Modular brick systems use 4" units.
- The nominal size of a modular brick is 4" x 2 2/3" x 8".
- A brick must be at least 75% solid to be considered solid.
Efflorescence
- Efflorescence is a white powder that forms on masonry walls after exposure to moisture.
Brick Positions
- A header brick is laid across two other bricks.
Types of Brick Bonds
- Common or American bond is a variation of the running bond.
- Headers are often used every five or seven courses in a common/American bond pattern.
- This bond has full-length headers within each pattern.
- Flemish bond is a specific brick pattern, (example pattern shown in images).
- Running bond is a specific brick pattern, (example pattern shown in images).
Brick Joint Types
- V-shaped or concave joints are recommended for areas exposed to harsh weather conditions (rain, wind, and freezing).
- Examples of various types of joints include: Trowel-struck, Flush, or Rough Cut joints, Raked joints,and Concave/rodded joints and Weathered joints.
Strengths of Different Brick Bonds
- Stack bond is considered the weakest form of brick bonding.
CMU (Concrete Masonry Unit) Information
- Pumice CMUs have the lowest density/weight per cubic foot of concrete.
- Sand and gravel are the highest strength aggregates in 8x8x16 CMUs.
- A standard 8x8x16 CMU made of sand and gravel weighs 40 lbs.
- The standard mortar joint size for CMUs is 3/8 inch.
- A two-core CMU has an advantage over three-core block design in terms of lighter weight and reduced heat conduction.
Building Materials
- The 8x8x16 size is a standard measurement for 8 inch stretcher blocks.
- A standard glass block mortar joint is 1/4 inch thick.
