,1. A technician is evaluating a condition; which response is most appropriate because
Advanced concrete technology includes mixture proportioning, materials evaluation,
statistics, and quality control.. Which answer best applies to the underlying NRMCA
technologist level 3 concept in this situation?
A. Absolute volume proportioning accounts for the absolute volumes of cementitious materials,
water, aggregates, admixtures, and air..
B. Statistical quality control helps distinguish normal variation from meaningful changes in
concrete performance..
C. Mixture calculations require consistent units, accurate specific gravities, and appropriate
target properties..
D. Advanced concrete technology includes mixture proportioning, materials evaluation,
statistics, and quality control..
Correct answer: D
Rationale: The correct choice directly states the governing principle: Advanced concrete
technology includes mixture proportioning, materials evaluation, statistics, and quality control..
The alternatives address related topics but do not directly answer the issue being tested.
2. Which choice correctly identifies the main reason that Absolute volume
proportioning accounts for the absolute volumes of cementitious materials, water,
aggregates, admixtures, and air.. Which answer best applies to the underlying NRMCA
technologist level 3 concept in this situation?
,A. Absolute volume proportioning accounts for the absolute volumes of cementitious materials,
water, aggregates, admixtures, and air..
B. Statistical quality control helps distinguish normal variation from meaningful changes in
concrete performance..
C. Strength evaluation should consider test results, variability, age, curing, and applicable
acceptance criteria..
D. Mixture calculations require consistent units, accurate specific gravities, and appropriate
target properties..
Correct answer: A
Rationale: The correct choice directly states the governing principle: Absolute volume
proportioning accounts for the absolute volumes of cementitious materials, water, aggregates,
admixtures, and air.. The alternatives address related topics but do not directly answer the
issue being tested.
3. When reviewing this equipment, which statement best applies because Mixture
calculations require consistent units, accurate specific gravities, and appropriate target
properties.. Which answer best applies to the underlying NRMCA technologist level 3
concept in this situation?
A. Aggregate properties influence workability, water demand, volume calculations, and
concrete performance..
B. Statistical quality control helps distinguish normal variation from meaningful changes in
concrete performance..
, C. Strength evaluation should consider test results, variability, age, curing, and applicable
acceptance criteria..
D. Mixture calculations require consistent units, accurate specific gravities, and appropriate
target properties..
Correct answer: D
Rationale: The correct choice directly states the governing principle: Mixture calculations
require consistent units, accurate specific gravities, and appropriate target properties.. The
alternatives address related topics but do not directly answer the issue being tested.
4. A supervisor asks which practice should guide the work when Statistical quality
control helps distinguish normal variation from meaningful changes in concrete
performance.. Which answer best applies to the underlying NRMCA technologist level 3
concept in this situation?
A. Aggregate properties influence workability, water demand, volume calculations, and
concrete performance..
B. Strength evaluation should consider test results, variability, age, curing, and applicable
acceptance criteria..
C. Statistical quality control helps distinguish normal variation from meaningful changes in
concrete performance..
D. Admixtures modify fresh or hardened properties and must be used at appropriate dosages..
Correct answer: C
