1. What is the primary purpose of post-tensioning in concrete
construction?
A. To increase the slump of concrete
B. To induce compressive stress and reduce tensile cracking
C. To accelerate curing time
D. To decrease concrete density
Post-tensioning introduces compressive forces into concrete
members, counteracting tensile stresses that would otherwise cause
cracking.
2. Which of the following materials is typically used for post-tensioning
tendons?
A. Carbon fiber
B. Glass rod
C. High-strength steel strand
D. Aluminum cable
High-strength steel strands are standard in post-tensioning due to
their superior tensile capacity and ductility.
,3. What is the correct sequence of operations in a bonded
post-tensioning system?
A. Stress, grout, place concrete
B. Place concrete, stress, grout
C. Grout, place concrete, stress
D. Place concrete, grout, stress
In bonded systems the tendon ducts are grouted after concrete
placement and then tensioned and bonded to the concrete.
4. Which of the following best describes “dead end” in post-tensioning?
A. A tendon that is not stressed
B. The far end of the tendon
C. The anchorage at one end that resists the entire tendon force
D. A tendon that is cut after stressing
The dead end anchorage takes the full force of the tendon when
tensions are applied.
5. What must be verified before stressing a tendon?
A. Weather conditions
B. Concrete mix design
C. Concrete has attained required strength
D. Rebar placement has begun
Post-tensioning can only be performed once concrete has reached the
specified compressive strength to resist the induced forces.
6. What is the typical minimum concrete compressive strength required
before post-tensioning?
A. 500 psi
B. 1,500 psi
C. 2,000 psi
D. 3,000 psi
, A 3,000 psi minimum is a standard requirement for many
post-tensioning specifications to ensure adequate concrete stiffness.
7. Which tool is used to apply tension to a post-tensioning strand?
A. Vibrator
B. Hydraulic jack
C. Sledgehammer
D. Torque wrench
Hydraulic jacks are used to tension tendons to the required force in
post-tensioning operations.
8. What is the purpose of grout in a bonded post-tensioning system?
A. To lubricate the strand
B. To accelerate curing
C. To bond the tendon to the concrete and provide corrosion
protection
D. To reduce the concrete’s strength
Grout fills the duct, bonding the tendon to the concrete and isolating
it from corrosive elements.
9. What is a stressing jack calibrated to measure?
A. Time of stress
B. Strain only
C. Force applied to the tendon
D. Concrete slump
The jack’s gauge measures the force applied during tensioning.
10. What should be done if the jack gauge reading is inconsistent
with expected values?
A. Ignore it
B. Continue stressing until concrete cracks
C. Stop and verify calibration and setup
D. Reduce concrete strength
