1. What is the primary purpose of mortar in a masonry wall?
A. To increase the weight of the wall
B. To replace reinforcing steel
C. To bond masonry units and accommodate minor irregularities
D. To waterproof the entire wall
Correct Answer: C. To bond masonry units and accommodate minor
irregularities
Rationale: Mortar bonds masonry units together, distributes loads
between uneven surfaces, and accommodates small dimensional
variations. Mortar is not intended to replace structural reinforcement
or serve as the sole waterproofing system.
, 2. Which mortar property is most important for allowing a mason to
properly spread and place mortar during construction?
A. Workability
B. Density
C. Electrical resistance
D. Thermal conductivity
Correct Answer: A. Workability
Rationale: Workability describes how easily mortar can be mixed,
spread, placed, and tooled. A workable mortar adheres adequately to
masonry units and can be manipulated without excessive segregation
or loss of cohesion.
3. What is the primary function of a masonry bond pattern?
A. To eliminate the need for mortar
B. To arrange masonry units so the wall acts as an integrated assembly
C. To make every wall waterproof
D. To reduce the need for foundations
Correct Answer: B. To arrange masonry units so the wall acts as an
integrated assembly
,Rationale: Bond patterns distribute loads and tie individual masonry
units together. Proper bonding improves wall stability and helps
transfer stresses through the masonry assembly.
4. In running bond masonry, vertical joints in successive courses are
generally:
A. Aligned continuously
B. Offset from one another
C. Filled only with grout
D. Eliminated completely
Correct Answer: B. Offset from one another
Rationale: Running bond typically places each masonry unit so its
vertical joints are offset from the joints in adjacent courses. This
arrangement improves the continuity and structural behavior of the
wall.
5. What is the purpose of a control joint in a concrete masonry wall?
A. To intentionally accommodate anticipated movement
B. To eliminate all wall movement
, C. To replace the foundation
D. To increase mortar strength
Correct Answer: A. To intentionally accommodate anticipated
movement
Rationale: Concrete masonry can experience shrinkage and other
dimensional changes. Properly located control joints help manage
these movements and reduce uncontrolled cracking.
6. Which material is commonly used to reinforce masonry walls
horizontally?
A. Reinforcing ladder or truss wire
B. Roofing felt only
C. Plastic sheeting
D. Wood shims
Correct Answer: A. Reinforcing ladder or truss wire
Rationale: Horizontal joint reinforcement is commonly incorporated
into mortar joints to help control cracking and improve the structural
performance of masonry walls. It must be installed at the required
locations and properly embedded.
