VERIFIED ANSWERS.
1. A prestressed concrete double-tee is an example of a post
tensioned member. - correct answer-false
2. At which stage in the life of a prestress member is the
prestress force the highest and the concrete compressive
strength the lowest? - correct answer-transfer
3. The following are examples of prestress losses in pre-
tensioned members except. - correct answer-Wobble
4. The eccentricity "e" of a prestressed members can best be
described as: - correct answer-The distance between the
center of gravity of the tendons and the neutral axis of the
member.

5. Given that f'c is 5,000 psi, what is the allowable compressive
stress at the transfer design stage at the end support of a
simply supported beam? - correct answer-3,500 psi
6. The purpose of draping the tendons in a post-tensioned slab
is... - correct answer-To balance the stresses that are
generated from the gravity loading.
7. Submitals as opposed to RFI's become a part of the contract
documents and thus it is important to make any major
changes to the construction documents within a submittal. -
correct answer-False
8. All of the following are example of submittals related to
reinforced concrete except... - correct answer-Erection
drawings
9. A concrete mix with a w/c ratio of 0.55 is more likely to have
numerous shrinkage cracks then a mix with a w/c ratio of
0.45. - correct answer-True

10. If a concrete sample has a higher slump than per the
approved mix design, which of the following is least likely to
be the cause. - correct answer-too much cement
11. Unreinforced concrete has a tensile strength roughly half
that of the compressive strength. - correct answer-False
12. All other items being equal, a mix with lower w/c ratio will
lead to a stronger mix that one with a higher w/c ratio. -
correct answer-True
13. Air entrainment is added to concrete to increase its
workability and compressive strength. - correct answer-False
14. Which of the following concrete finishes is not
recommended for a concrete mix with a high amount of air
entrainment (4-6%). - correct answer-Hard Steel Trowel
Finish
15. The purpose of control joints is to keep the slab from
cracking. - correct answer-False-The purpose is to force the
