NETTCP Concrete Inspector Questions and
Verified Answers
Quality assurance is defined as only those planned and systematic actions taken by the
agency to provide confidence that a product or facility will perform satisfactorily in
service. (1-1)
Ans: False
A quality assurance program serves as a skeleton or overall framework necessary for
construction quality assurance implementation. (1-4)
Ans: True
Joint development and review of quality assurance specifications should include agency
and industry personnel (engineers, inspectors, technicians) who are directly responsible
for construction. (1-5)
Ans: True
The same six core elements required for design-bid-build construction QA programs are
also required for design-build construction QA programs. (1-8)
Ans: True
Quality control activities include only sampling and testing. Visual inspection is
relegated to the acceptance inspector. (1-10)
Ans: False
Quality control plans are project specific documents whose function is to address specific
production facility and field placement processes for individual categories of work on a
construction project. (1-11)
Ans: True
Acceptance is the responsibility of the transportation agency. (1-12)
Ans: True
The engineering limits are the absolute threshold values for individual test results (1-15)

Ans: True
Quality assurance specifications typically use quality measures. (1-14)
Ans: True
Since the objective of the IA comparison is to identify discrepancies or variability in
testing procedures or equipment, IA testing is performed on split samples. (1-20)
Ans: True
If Contractor QC test results are not utilized in the acceptance decision, a dispute
resolution system is not required. (1-21)
Ans: True
All Agency Central Laboratories are required under federal regulations to be accredited
through AASHTO Accreditation Program (AAP). (1-23)
Ans: True
Personal Qualification/Certification programs should include requirements for re-
certification at 2 to 5 year intervals. (1-26)
Ans: True
Each Agency Construction QA Program must meet the requirements of 23 CFR 637B and
is required to be approved by FHWA. (1-27)
Ans: True
The process of hydration begins immediately when the cement comes in contact with
water. (2-1)
Ans: True
The cement paste density and strength are related. (2-1)
Ans: True
AASHTO M 85 (ASTM C 150) stipulate cement types based on chemical composition. (2-
3)
Ans: True

Type III cement is known as a low heat of hydration cement. (2-3)
Ans: False
According to ACI 318, mixtures using Type I cement should be cured for 7 days. (2-4)
Ans: True
Lowering the heat of hydration in massive concrete structures is important to prevent
thermal cracking. (2-4)
Ans: True
A type IP(10) is used to indicate a Portland-pozzolan blended product, with 10%
pozzolan. (2-5)
Ans: True
Expansive cement is a special product designed to offset stresses in concrete caused by
drying shrinkage, which when excessive can lead to cracking. (2-6)
Ans: True
The time of set for cement paste is determined via a needle penetration method. (2-7)
Ans: True
Cement should be stored in humid or moist environments to ensure hydration has
started prior to being introduced into the concrete mixer. (2-8)
Ans: False
A pozzolan is a material which in itself possesses little or no cementitious activity, but
when combined with hydraulic cement, will behave in a cementitious manner. (3-1)
Ans: True
Fly ash tends to increase the consistency of concrete when compared to mixtures with
just Portland Cement. (3-3)
Ans: True
Dosages of air entrainment generally need to be lowered when fly ash is used. (3-3)
