Concrete Masonry Units (CMU)
Foundation Walls
Structural Support Walls (low rise)
Backup Walls for Exterior Facing
Brick & Stone
Facing Materials - Veneers
Decorative Walls

8. Brick Masonry - Sizes and Shapes
No standard size
Normal coursing - 3 bricks = 8”
Larger sizes
Custom Shapes & Colors

9. Brickwork Strength Depends on: Strength of the masonry unit
Strength of the mortar

10. TERMINOLOGY, BONDS AND JOINTS IN BRICK MASONRY
Terminology used in laying bricks: Bed joint, Head joint, Collar joint, Wythe, Stretcher, Header, Soldier, Rowlock
Structural bonds used during brick laying
Running Bond: All courses of brick made of stretchers, with breaking of joints, from one course to the other
English Bond: made of alternate courses of stretchers and headers, with breaking of joints
Common Bond or American Bond : Made of stretchers courses, with every sixth course being made completely of headers, with breaking of joints
Flemish Bond: In the same layer ( or course) stretchers and headers are laid alternatively, with breaking of joints

11. Basic Brickwork Terminology
Head
Joint
Bed
Joint
Course - horizontal layer of brick

12. TERMINOLOGY, BONDS AND JOINTS IN BRICK MASONRY
Procedure for building brick walls: (i) Laying of lead (or corner bricks) to establish the wall planes and courses heights - (ii) Bricks in between leads are laid to a line ( a heavy string stretchers taut between line blocks at each lead)
Joint Tooling:
Required for giving beauty to mortar joints
Weathered Joint: Mortar joint has sloped (downwards) edge
Concave joint: Joint concave inwards
Vee joint: mortar joint is in the form of a V
Flush Joint: Mortar joint is flush with the brick surfaces
Raked Joint: A large portion of the mortar joint is raked out - Not a safe, impermeable joint
Struck Joint: Mortar joint has a sloped (upwards) edge
Mortar joints can vary from 1/4” to 1/2” - Usually taken as 3/8”

14. TYPES OF BRICK MASONRY WALLS AND STRUCTURES
Reinforced Brick Masonry:
A reinforced brick masonry wall in constructed with two wythes of brick, 2” to 4” apart, placing the reinforced steel in the cavity and filling the cavity with grout. Grout is a mixture of Portland cement, aggregate and water. Grout must be filled enough to flow readily into the narrow cavity and fill it completely - Two methods are used in building reinforced brick walls
Low-lift method: Height of grout filling is not more than 4 feet - Wythes are held together by galvanized steel wire ties at 24” c/c horizontally and 16” c/c vertically.
High-lift method: Wall is grouted, one story at a time - Clean out holes are left at the bottom to drive out the debri (from mortar in brick masonry) down with water through the holes - Finally the clean out holes are sealed with a brick and mortar joint.
