West Virginia (WV) Masonry Contractor Exam | Latest
Verified Questions and Detailed Answers
OVERVIEW DESCRIPTION:
This collection of unique multiple-choice questions is designed for the West Virginia
Masonry Contractor Exam. It comprehensively covers the key exam topics, including
masonry components (brick, block, glass block, stone), mortar and reinforcement types
and applications, construction techniques (bonds, lintels, joints, wall construction), plan
reading and material estimating, OSHA safety regulations and scaffolding requirements,
and IBC code provisions. Each question includes a correct answer and a concise expert
rationale, offering targeted review for both code knowledge and practical field judgment.
QUESTION 1
Which type of brick is specifically manufactured with a textured face to resemble natural
stone, often used for aesthetic facades?
A) Fire brick
B) Clinker brick
C) Sand-lime brick
D) Rock-faced brick
CORRECT ANSWER: D
EXPERT RATIONALE: Rock-faced brick has a rough, stone-like texture on one face,
created by pressing the brick against a rock-surfaced mold, enhancing appearance
without affecting structural integrity.
QUESTION 2
What is the minimum compressive strength (ASTM C90) for a standard concrete
,2|Page
masonry unit (CMU) in non-load-bearing applications?
A) 1,000 psi
B) 1,900 psi
C) 600 psi
D) 2,500 psi
CORRECT ANSWER: C
EXPERT RATIONALE: ASTM C90 requires non-load-bearing CMUs to have a minimum
compressive strength of 600 psi; load-bearing CMUs require 1,900 psi.
QUESTION 3
In a running bond pattern, how are the vertical joints aligned?
A) Aligned vertically every third course
B) Centered over the unit below in alternate courses
C) Offset by half the unit’s length in each successive course
D) Stacked directly above each other
CORRECT ANSWER: C
EXPERT RATIONALE: Running bond offsets vertical joints by half a brick or block length
in each course, providing the strongest interlocking for wall stability.
QUESTION 4
What is the primary function of a lintel in masonry construction?
A) To control vertical expansion
,3|Page
B) To support the load above an opening (door/window)
C) To drain water from the wall cavity
D) To reinforce the mortar bed joint
CORRECT ANSWER: B
EXPERT RATIONALE: A lintel is a horizontal structural member that transfers the weight
of masonry above an opening to adjacent wall sections.
QUESTION 5
According to IBC, what is the maximum height of a masonry scaffold without
engineering design if using standard tube and coupler components?
A) 25 feet
B) 35 feet
C) 125 feet
D) No height limit
CORRECT ANSWER: C
EXPERT RATIONALE: IBC and OSHA allow tube-and-coupler scaffolds up to 125 feet
without custom engineering if manufacturer’s instructions and load ratings are followed.
QUESTION 6
Which mortar type (ASTM C270) has the lowest compressive strength and is used only
for interior, non-load-bearing partitions?
A) Type N
, 4|Page
B) Type O
C) Type S
D) Type M
CORRECT ANSWER: B
EXPERT RATIONALE: Type O mortar has a compressive strength of about 350 psi,
suitable only for interior non-load-bearing walls due to very low structural capacity.
QUESTION 7
How many standard modular bricks (3 5/8″ × 2 1/4″ × 7 5/8″) are needed per square
foot of a wall laid in running bond with 3/8″ mortar joints?
A) 4.5
B) 6.75
C) 5.2
D) 7.0
CORRECT ANSWER: B
EXPERT RATIONALE: Including mortar joints, each brick covers about 2.67″ × 8″ =
21.36 sq in; .36 ≈ 6.75 bricks per sq ft.
QUESTION 8
What does the “H” in the OSHA “H-type” scaffold frame refer to?
A) High load capacity
B) Horizontal bracing configuration
