repair is performed correctly?
A. Immediately remove all damaged bricks without inspection
B. Review the structural condition, determine the cause of deterioration,
and establish a repair plan
C. Apply mortar over the damaged areas to conceal defects
D. Replace all masonry materials with concrete regardless of existing
construction
Answer: B
A proper masonry repair begins with identifying the cause and extent of
damage. A supervisor must evaluate structural conditions and develop an
appropriate repair strategy before directing workers.
, 2. Which type of mortar is generally recommended for historic brick
restoration because it provides better compatibility with older, softer
masonry units?
A. High-strength Portland cement mortar
B. Epoxy adhesive mortar
C. Lime-based mortar
D. Steel-reinforced grout mortar
Answer: C
Lime-based mortar is often used in historic masonry because it is softer and
more flexible than modern high-strength mortars, reducing damage to
older bricks.
3. When supervising masonry workers on a hospital construction site,
the primary responsibility of the supervisor regarding safety is to:
A. Allow workers to determine their own safety procedures
B. Ensure compliance with OSHA regulations and site safety requirements
C. Eliminate all inspections to increase productivity

powder appearing on the surface. This condition is known as:
A. Efflorescence
B. Scaling
C. Spalling
D. Delamination
Answer: A
Efflorescence occurs when soluble salts migrate through masonry and

project. Which factor must be considered besides wall dimensions?
A. Worker clothing requirements
B. Brick size, mortar joints, and waste allowance
C. Weather forecast only
D. Paint color selection
Answer: B
Accurate masonry estimates require consideration of unit size, mortar
thickness, and additional materials needed due to breakage and cutting.
9. When laying bricks, the primary purpose of mortar joints is to:
A. Increase wall weight only
B. Bond masonry units together and distribute loads
C. Replace the need for foundations
D. Prevent all moisture movement
Answer: B
Mortar joints provide bonding between masonry units, help distribute
