1. A cement mason apprentice is primarily responsible for which activity
on a construction site?
A. Designing structural steel reinforcement layouts
B. Inspecting electrical wiring systems in concrete slabs
C. Mixing, placing, finishing, and curing concrete surfaces
D. Operating cranes for lifting precast concrete panels
Correct Answer: C
A cement mason apprentice focuses on handling concrete work such as
mixing, placing, finishing, and curing surfaces like floors, sidewalks, and
pavements, which are core duties of the trade.
2. Which of the following best describes the first step before concrete
placement begins?
A. Installing roofing membranes
B. Setting forms and preparing the site
,C. Painting cured concrete surfaces
D. Removing scaffolding systems
Correct Answer: B
Before concrete is poured, forms must be set and the site prepared to
ensure the concrete is properly shaped and supported during placement.
3. What is the primary purpose of reinforcing steel (rebar) in concrete
work?
A. To reduce concrete curing time
B. To improve color consistency of concrete
C. To increase tensile strength of concrete structures
D. To make concrete lighter in weight
Correct Answer: C
Rebar is used to strengthen concrete in tension, since concrete is naturally
strong in compression but weak in tensile forces.
4. Which tool is most commonly used to level freshly poured concrete?
A. Trowel
B. Hammer drill
C. Straightedge screed
D. Masonry chisel
Correct Answer: C
A screed or straightedge is used to level and strike off excess concrete to
create a flat surface after pouring.
5. What is the main function of curing concrete?
A. Accelerating drying through heat application
B. Allowing concrete to gain strength and durability over time
,C. Removing excess water immediately after pouring
D. Changing the color of the concrete surface
Correct Answer: B
Curing allows concrete to maintain moisture so it can properly hydrate and
gain strength and durability over time.
6. Which factor most directly affects how quickly concrete sets on site?
A. Color of cement powder
B. Weather conditions such as temperature and wind
C. Type of construction gloves used
D. Number of workers on site
Correct Answer: B
Temperature, humidity, and wind significantly influence concrete setting
time and finishing conditions on site.
7. What is the purpose of expansion joints in concrete structures?
A. To increase surface smoothness
B. To allow movement due to temperature changes
C. To strengthen decorative patterns
D. To reduce material cost
Correct Answer: B
Expansion joints allow concrete to expand and contract with temperature
changes without cracking.
8. Which of the following is a common finishing tool used in cement
masonry?
A. Bull float
B. Pipe wrench
, C. Wire stripper
D. Torque wrench
Correct Answer: A
A bull float is used to smooth and level the surface of freshly placed
concrete before final finishing.
9. What is the role of formwork in concrete construction?
A. To color the concrete surface
B. To hold concrete in the desired shape until it hardens
C. To test the strength of cured concrete
D. To waterproof steel beams
Correct Answer: B
Formwork acts as a mold that supports wet concrete until it gains enough
strength to hold its shape.
10. Which safety equipment is essential when working with wet
concrete?
A. Safety gloves and eye protection
B. Sandals and shorts
C. Earplugs only
D. Lightweight clothing only
Correct Answer: A
Protective gloves and eye protection are necessary because wet concrete is
caustic and can cause burns or irritation.
11. What is the purpose of a float in concrete finishing?
A. To break concrete into smaller pieces
B. To smooth and compact the surface after screeding
