NETTCP CONCRETE INSPECTOR QUESTIONS WITH
VERIFIED ACCURATE ANSWERS
False - 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)
True - Answers - A quality assurance program serves as a skeleton or overall
framework necessary for construction quality assurance implementation. (1-4)
True - Answers - 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 - Answers - 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 - Answers - Quality control activities include only sampling and testing. Visual
inspection is relegated to the acceptance inspector. (1-10)
True - Answers - 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 - Answers - Acceptance is the responsibility of the transportation agency. (1-12)
True - Answers - The engineering limits are the absolute threshold values for individual
test results (1-15)
True - Answers - Quality assurance specifications typically use quality measures. (1-14)
True - Answers - 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 - Answers - If Contractor QC test results are not utilized in the acceptance
decision, a dispute resolution system is not required. (1-21)
True - Answers - All Agency Central Laboratories are required under federal regulations
to be accredited through AASHTO Accreditation Program (AAP). (1-23)
True - Answers - Personal Qualification/Certification programs should include
requirements for re-certification at 2 to 5 year intervals. (1-26)
, True - Answers - Each Agency Construction QA Program must meet the requirements
of 23 CFR 637B and is required to be approved by FHWA. (1-27)
True - Answers - The process of hydration begins immediately when the cement comes
in contact with water. (2-1)
True - Answers - The cement paste density and strength are related. (2-1)
True - Answers - AASHTO M 85 (ASTM C 150) stipulate cement types based on
chemical composition. (2-3)
False - Answers - Type III cement is known as a low heat of hydration cement. (2-3)
True - Answers - According to ACI 318, mixtures using Type I cement should be cured
for 7 days. (2-4)
True - Answers - Lowering the heat of hydration in massive concrete structures is
important to prevent thermal cracking. (2-4)
True - Answers - A type IP(10) is used to indicate a Portland-pozzolan blended product,
with 10% pozzolan. (2-5)
True - Answers - 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 - Answers - The time of set for cement paste is determined via a needle
penetration method. (2-7)
False - Answers - 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 - Answers - 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 - Answers - Fly ash tends to increase the consistency of concrete when compared
to mixtures with just Portland Cement. (3-3)
False - Answers - Dosages of air entrainment generally need to be lowered when fly
ash is used. (3-3)
True - Answers - When compared to mixtures using just Portland cement, mixtures
supplemented with Grade 120 slag cement have greater 28 day strength. (3-5)
True - Answers - Fly ash and slag retard the set time of concrete. (3-8)
