1. What is the primary responsibility of a licensed concrete contractor on
a construction project?
A. To perform or supervise concrete work in accordance with approved
plans, specifications, applicable codes, contract requirements, safety
regulations, and accepted construction practices
B. To select concrete materials solely according to the lowest available price
C. To allow unqualified personnel to independently perform all regulated
concrete work
D. To modify structural concrete details without authorization
Answer: A. To perform or supervise concrete work in accordance with
approved plans, specifications, applicable codes, contract requirements,
safety regulations, and accepted construction practices
,Rationale: A concrete contractor is responsible for ensuring that concrete
operations comply with the project documents, applicable requirements,
and proper construction practices while maintaining quality and safety.
2. Before placing structural concrete, which information should the
contractor verify most carefully?
A. Approved drawings, concrete specifications, mix requirements,
reinforcement details, dimensions, embedded items, formwork,
construction joints, and inspection requirements
B. Only the desired concrete color
C. Only the number of workers available
D. Only the delivery truck capacity
Answer: A. Approved drawings, concrete specifications, mix requirements,
reinforcement details, dimensions, embedded items, formwork,
construction joints, and inspection requirements
Rationale: Concrete placement depends on accurate coordination of
structural, material, reinforcement, formwork, and inspection
requirements before concrete arrives at the site.
3. What is the primary purpose of concrete formwork?
A. To contain and support fresh concrete until it has developed sufficient
strength and shape to support itself
,B. To permanently replace structural reinforcement
C. To increase the water content of concrete
D. To eliminate the need for curing
Answer: A. To contain and support fresh concrete until it has developed
sufficient strength and shape to support itself
Rationale: Formwork establishes the required geometry and supports fresh
concrete and construction loads until the concrete can safely carry the
applicable loads.
4. Which characteristic is most important when evaluating concrete
formwork before placement?
A. Adequate strength, stiffness, alignment, dimensions, stability, cleanliness,
and support for the expected concrete and construction loads
B. Decorative appearance only
C. Maximum flexibility during placement
D. Ability to absorb water from the concrete
Answer: A. Adequate strength, stiffness, alignment, dimensions, stability,
cleanliness, and support for the expected concrete and construction loads
Rationale: Deficient formwork can move, deform, leak, or collapse,
resulting in dimensional defects, poor finishes, or serious safety hazards.
5. Why must formwork be adequately braced?
, A. Bracing resists lateral and other construction forces and helps maintain
the required position and geometry during concrete placement
B. Bracing increases the concrete water-cement ratio
C. Bracing eliminates reinforcement
D. Bracing prevents concrete from curing
Answer: A. Bracing resists lateral and other construction forces and helps
maintain the required position and geometry during concrete placement
Rationale: Fresh concrete exerts significant lateral pressure on forms,
particularly during rapid placement, so adequate bracing is essential for
stability.
6. What is concrete's water-cement ratio?
A. The ratio of the mass of water to the mass of cementitious material in a
concrete mixture
B. The ratio of aggregate volume to formwork volume
C. The ratio of cement volume to reinforcement weight
D. The ratio of water to coarse aggregate only
Answer: A. The ratio of the mass of water to the mass of cementitious
material in a concrete mixture
Rationale: The water-cementitious-material ratio is a major factor
influencing concrete strength, durability, permeability, and workability.
