NETTCP Concrete Inspector Exam
False 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)
True A quality assurance program serves as a skeleton or overall framework
necessary for construction quality assurance implementation. (1-4)
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)
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)
False Quality control activities include only sampling and testing. Visual inspection is
relegated to the acceptance inspector. (1-10)
True 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)
True Acceptance is the responsibility of the transportation agency. (1-12)
True The engineering limits are the absolute threshold values for individual test
results (1-15)
True Quality assurance specifications typically use quality measures. (1-14)
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)
True If Contractor QC test results are not utilized in the acceptance decision, a
dispute resolution system is not required. (1-21)
True All Agency Central Laboratories are required under federal regulations to be
accredited through AASHTO Accreditation Program (AAP). (1-23)
, NETTCP Concrete Inspector Exam
True Personal Qualification/Certification programs should include requirements for
re-certification at 2 to 5 year intervals. (1-26)
True Each Agency Construction QA Program must meet the requirements of 23 CFR
637B and is required to be approved by FHWA. (1-27)
True The process of hydration begins immediately when the cement comes in
contact with water. (2-1)
True The cement paste density and strength are related. (2-1)
True AASHTO M 85 (ASTM C 150) stipulate cement types based on chemical
composition. (2-3)
False Type III cement is known as a low heat of hydration cement. (2-3)
True According to ACI 318, mixtures using Type I cement should be cured for 7 days.
(2-4)
True Lowering the heat of hydration in massive concrete structures is important to
prevent thermal cracking. (2-4)
True A type IP(10) is used to indicate a Portland-pozzolan blended product, with
10% pozzolan. (2-5)
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)
True The time of set for cement paste is determined via a needle penetration
method. (2-7)
False Cement should be stored in humid or moist environments to ensure hydration
has started prior to being introduced into the concrete mixer. (2-8)
True 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)
True Fly ash tends to increase the consistency of concrete when compared to
mixtures with just Portland Cement. (3-3)
False Dosages of air entrainment generally need to be lowered when fly ash is used.
