1. Which of the following ASTM standards covers the specification for
deformed and plain carbon-steel bars for concrete reinforcement?
A. ASTM A53
B. ASTM A615
C. ASTM A36
D. ASTM A992
ASTM A615 specifies requirements for deformed and plain carbon-
steel bars for concrete reinforcement.
2. The primary purpose of rebar chairs and supports in concrete
construction is to:
A. Reduce concrete curing time
B. Maintain correct reinforcement positioning
C. Prevent corrosion of the bars
D. Increase concrete tensile strength
Rebar chairs and supports ensure the reinforcement remains in the
correct position during concrete placement.
,3. What minimum clear distance must be maintained between parallel
reinforcing bars having sizes #5 and smaller when using normal-weight
concrete?
A. ½ inch
B. 1 inch
C. 1½ inches
D. 2 inches
A minimum clear spacing of 1 inch is required to allow proper
concrete consolidation.
4. Which of the following rebar sizes corresponds to a nominal diameter
of 3/8 inch?
A. #4
B. #3
C. #3
D. #5
Rebar size #3 has a nominal diameter of 3/8 inch.
5. Rebar laps must be spliced according to code to avoid structural
weaknesses. For tension splices, what is the approximate minimum lap
length for a #6 bar in normal-weight concrete?
A. 15 inches
B. 36 inches
C. 24 inches
D. 45 inches
The minimum lap length for a #6 bar in tension is approximately 36
inches in normal-weight concrete.
6. Which rebar bending schedule detail identifies the angle at which a
bar is bent?
A. Hook length
B. Leg length
, C. Bend angle
D. Bar mark
The bend angle specifies the degree of the bar’s bend.
7. What is the main purpose of epoxy coating on reinforcing steel?
A. To strengthen the steel
B. To protect against corrosion
C. To improve weldability
D. To increase ductility
Epoxy coatings protect reinforcing steel from corrosive environments.
8. Which testing method is used to determine the yield strength of
reinforcing steel?
A. Concrete compression test
B. Tensile test
C. Slump test
D. Bend and rebend test
A tensile test determines yield strength and ultimate strength of
reinforcing steel.
9. In seismic design categories, what is the primary concern for rebar
detailing?
A. Aesthetic appearance
B. Ductility and energy dissipation
C. Cost reduction
D. Thermal conductivity
Seismic detailing focuses on ductility and energy dissipation during
earthquakes.
10. What is the maximum permissible bar diameter for dowel bars in
expansion joints unless specified otherwise?
A. #8
B. No maximum specific size unless engineered
