1. Which of the following is the primary purpose of mortar in masonry
construction?
A. To provide thermal insulation
B. To bond masonry units together and distribute loads
C. To prevent all water infiltration
D. To serve as a decorative element
To bond masonry units together and distribute loads
Mortar serves as the structural adhesive that holds individual masonry units
in place, transferring loads between units and accommodating minor
dimensional variations in the masonry units.
2. What is the standard proportion of Portland cement, lime, and sand in
Type N mortar?
A. 1:0.5:3
B. 1:1:6
C. 1:0.25:3
D. 1:1:4
1:1:6
,Type N mortar typically consists of 1 part Portland cement, 1 part lime, and 6
parts sand. This combination offers medium compressive strength (750 psi)
suitable for above-grade exterior and interior load-bearing walls.
3. Which tool is specifically used to finish horizontal joints in masonry?
A. Trowel
B. Jointer
C. Plumb bob
D. Chisel
Jointer
A jointer (also called a joint runner) is designed to compress and shape
mortar joints, improving both appearance and water resistance. Horizontal
bed joints are commonly finished with a concave or V-shaped jointer.
4. What is the standard nominal size for a modular brick?
A. 2 1/4 × 3 3/4 × 7 5/8 inches
B. 2 × 4 × 8 inches
C. 3 × 6 × 12 inches
D. 4 × 8 × 16 inches
2 1/4 × 3 3/4 × 7 5/8 inches
Modular bricks follow the nominal size of 2 1/4 × 3 3/4 × 7 5/8 inches to allow
for 3/8-inch mortar joints, resulting in a standard 4-inch wall module when
laid.
5. Which type of bond is most commonly used in modern brick walls?
A. Flemish bond
B. English bond
C. Running bond
D. Stack bond
,Running bond
Running bond, consisting of bricks offset by half a brick length per course, is
the most widely used bond in modern masonry due to its simplicity, strength,
and efficient load distribution.
6. The process of wetting bricks before laying them is primarily done to:
A. Improve color uniformity
B. Prevent mortar shrinkage
C. Reduce moisture absorption from the mortar
D. Increase joint thickness
Reduce moisture absorption from the mortar
Pre-wetting highly porous bricks prevents them from drawing water out of
the mortar too quickly, which can weaken the bond and reduce the mortar's
workability and curing potential.
7. Which type of brick is best suited for exterior walls in areas with high
moisture exposure?
A. Sand-lime brick
B. Firebrick
C. Concrete brick
D. Common clay brick
Concrete brick
Concrete bricks are dense and highly resistant to moisture penetration,
making them suitable for exterior walls in wet conditions. Firebricks are for
high-temperature applications, not moisture resistance.
8. What is the primary purpose of a header course in brick masonry?
A. Decorative finish
B. To tie two wythes of masonry together
, C. To improve insulation
D. To provide a base for the first course
To tie two wythes of masonry together
Header courses interlock wythes (vertical layers of masonry), ensuring
structural stability in multi-wythe walls by connecting the inner and outer
layers.
9. The standard thickness of a mortar joint in most brick masonry is:
A. 1/8 inch
B. 3/8 inch
C. 1/2 inch
D. 1 inch
3/8 inch
A 3/8-inch joint is standard for brickwork, balancing strength, workability,
and accommodation of minor brick dimensional variations.
10. Which type of bond is commonly used in cavity wall construction?
A. English bond
B. Stretcher bond
C. Flemish bond
D. Stack bond
Stretcher bond
Stretcher bond is typical in cavity walls because it efficiently ties the wall
together while allowing a cavity space between the inner and outer wythes
for drainage and insulation.
11. Which mortar type is strongest and least workable?
A. Type M
B. Type S
