INTRODUCTION
The Louisiana Masonry, Brick & Stone Contractor Exam – Classification 1.7 assesses the knowledge and
skills required for competent performance in the masonry construction trade. The examination
evaluates foundational theory, applied professional knowledge, technical concepts, regulatory
compliance, and ethical standards. Questions are presented in multiple-choice and scenario-based
formats, emphasizing real-world application and professional decision-making. Candidates must
demonstrate critical thinking, problem-solving, and the ability to interpret specifications, execute
proper techniques, and adhere to safety and legal requirements. This comprehensive assessment
prepares candidates for the responsibilities of a licensed masonry contractor in Louisiana.
SECTION ONE – QUESTIONS 1–100
Question 1
What is the primary purpose of mortar in masonry construction?
A. To increase the compressive strength of individual masonry units
B. To bond masonry units together and accommodate minor irregularities
C. To serve as the primary load-bearing component of the wall
D. To prevent all moisture from entering the wall assembly
🟢 B. To bond masonry units together and accommodate minor irregularities
🔴 Explanation: Mortar's primary functions are to bond units into a cohesive assembly, distribute
loads, and accommodate dimensional variations in masonry units. It is not intended as the primary
structural element or as a complete moisture barrier.
Question 2
Which mortar type generally exhibits the highest compressive strength?
,A. Type O
B. Type N
C. Type S
D. Type M
🟢 D. Type M
🔴 Explanation: Type M mortar has the highest compressive strength (approximately 2500 psi) among
standard mortar types and is used for below-grade and heavy-load applications.
Question 3
In masonry construction, the term "coursing" refers to:
A. The method of mixing mortar
B. The arrangement of masonry units in horizontal layers
C. The process of cleaning finished masonry
D. The pattern of reinforcement placement
🟢 B. The arrangement of masonry units in horizontal layers
🔴 Explanation: Coursing describes the systematic arrangement of masonry units in horizontal rows
(courses) to maintain consistent elevation and achieve the desired bond pattern.
Question 4
A masonry unit laid with its short end exposed on the wall face is called a:
A. Stretcher
B. Header
C. Soldier
D. Sailor
🟢 B. Header
🔴 Explanation: A header is a masonry unit laid with its short end facing the wall surface, typically used
to tie wythes together or create decorative patterns.
Question 5
Efflorescence on masonry surfaces appears as:
A. Dark, oily stains
B. Green mold growth
C. White, crystalline deposits
D. Rust-colored streaks
🟢 C. White, crystalline deposits
🔴 Explanation: Efflorescence is a deposit of water-soluble salts that migrate to the masonry surface
and crystallize as water evaporates, appearing as a white powdery or crystalline substance.
Question 6
The nominal thickness of a standard brick wythe is:
,A. 2 inches
B. 4 inches
C. 6 inches
D. 8 inches
🟢 B. 4 inches
🔴 Explanation: A single wythe of standard brick masonry is nominally 4 inches thick, accounting for
the brick's actual width plus the mortar joint.
Question 7
The standard recommended thickness for mortar joints in brick masonry is:
A. 1/8 inch
B. 1/4 inch
C. 3/8 inch
D. 1/2 inch
🟢 C. 3/8 inch
🔴 Explanation: Standard masonry practice specifies nominal 3/8-inch mortar joints for brick masonry
to ensure proper bonding and structural performance.
Question 8
Which tool is primarily used for spreading and shaping mortar during masonry installation?
A. Chisel
B. Float
C. Trowel
D. Jointer
🟢 C. Trowel
🔴 Explanation: The mason's trowel is the primary tool for picking up, placing, spreading, and shaping
mortar during masonry installation.
Question 9
Flashing in masonry walls is installed to:
A. Reinforce the wall against lateral loads
B. Direct water out of the wall assembly
C. Increase the thermal insulation value
D. Improve the aesthetic appearance
🟢 B. Direct water out of the wall assembly
🔴 Explanation: Flashing prevents water penetration by collecting moisture that enters the wall and
directing it to the exterior through weep holes or drainage systems.
Question 10
Weep holes are installed in masonry walls to:
, A. Provide ventilation for the building interior
B. Anchor the masonry to the structural frame
C. Allow water drainage from wall cavities
D. Accommodate thermal expansion
🟢 C. Allow water drainage from wall cavities
🔴 Explanation: Weep holes are small openings at the base of masonry walls or above flashing that
allow accumulated moisture to drain from the wall cavity.
Question 11
Which of the following stones is classified as igneous?
A. Limestone
B. Marble
C. Granite
D. Slate
🟢 C. Granite
🔴 Explanation: Granite is an igneous rock formed from cooled magma or lava, while limestone and
marble are sedimentary or metamorphic, and slate is metamorphic.
Question 12
Limestone is primarily composed of:
A. Calcium carbonate
B. Silica
C. Feldspar
D. Mica
🟢 A. Calcium carbonate
🔴 Explanation: Limestone is a sedimentary rock composed primarily of calcium carbonate (calcite),
often formed from the accumulation of marine organisms.
Question 13
Which mortar type is most appropriate for historic brick restoration where the existing brick is
relatively soft?
A. Type M
B. Type S
C. Type N
D. Type O
🟢 D. Type O
🔴 Explanation: Type O mortar has the lowest compressive strength (approximately 350 psi), making it
compatible with soft historic bricks and reducing the risk of spalling or damage to the original
masonry.
Question 14
The slump of mortar for typical masonry construction should generally be in the range of:
