MASONRY FIELD TESTING TECHNICIAN CERTIFICATION
EXAMINATION COMPLETE QUESTIONS AND DETAILED
SOLUTIONS LATEST UPDATE THIS YEAR JUST RELEASED
1. During field testing of masonry materials, what is the primary reason a
technician must obtain representative samples from the construction
materials?
A. To reduce the amount of laboratory testing required
B. To ensure the specimens accurately represent the material being
evaluated
C. To make the contractor's production process faster
D. To eliminate the need for project specifications
Answer: B
Rationale: Representative sampling is essential because test results are
meaningful only when the specimens accurately represent the material
placed or delivered for construction.
2. Before beginning any masonry field test, which information should the
technician verify to ensure the correct procedure and acceptance criteria
are being followed?
A. Only the contractor's preferred testing method
B. The project requirements, applicable ASTM method, and specified
material requirements
C. Only the weather forecast and delivery schedule
D. The manufacturer's advertising literature
Answer: B
,Rationale: Proper testing requires knowing the applicable ASTM procedure
and project requirements so that sampling, testing, and interpretation are
performed correctly.
3. When sampling brick or structural clay tile for testing, why is careful
identification and marking of specimens particularly important?
A. It allows specimens to be distinguished and associated with their source
or lot
B. It increases the compressive strength of the specimens
C. It eliminates dimensional measurements
D. It prevents the need for written records
Answer: A
Rationale: Identification provides traceability between specimens, material
lots, locations, deliveries, and test records.
4. A technician receives several masonry units for testing and notices loose
dirt and debris on their surfaces. What should generally be done before
obtaining required physical measurements?
A. Add water to the units
B. Remove loose material without damaging the specimens
C. Coat the units with mortar
D. Grind all surfaces smooth
Answer: B
Rationale: Loose debris can affect measurements and weight
determinations, but cleaning must not alter the specimen itself.
,5. Why should a masonry testing technician avoid damaging a brick while
preparing or handling it for dimensional testing?
A. Damage can alter the measured physical properties and invalidate the
test
B. Damage always makes the specimen heavier
C. Damaged bricks automatically become stronger
D. Damage only affects appearance and never test results
Answer: A
Rationale: Chipping, cracking, grinding, or otherwise altering a specimen can
change its dimensions, weight, or structural behavior and compromise the
result.
6. When determining dimensions of masonry units, why should
measurements be taken carefully at the locations required by the
applicable ASTM procedure?
A. Different locations can produce different dimensional results
B. Measurements are only required for aesthetic purposes
C. Any random location always produces identical results
D. The dimensions do not affect reported results
Answer: A
Rationale: Masonry units may have dimensional variations, so standardized
measurement locations promote consistent and comparable results.
7. A technician records a unit dimension as 7.62 cm when the instrument
actually reads 7.68 cm. What is the most appropriate response?
, A. Leave the value unchanged
B. Correct the measurement and verify the remaining recorded data
C. Average it with an unrelated specimen
D. Delete the entire test
Answer: B
Rationale: Accurate documentation is part of reliable testing. A discovered
measurement error should be corrected according to proper recordkeeping
procedures.
8. Why is specimen identification particularly important when multiple
brick or tile lots are being tested on the same project?
A. It allows results to be assigned to the correct material population
B. It eliminates the need for sampling
C. It makes all specimens equivalent
D. It prevents technicians from using measuring devices
Answer: A
Rationale: Traceability allows the technician and project personnel to
determine which material lot produced a particular test result.
9. What is the primary concern when transporting masonry test specimens
from the construction site to another testing location?
A. Keeping specimens identifiable and protected from damage or
contamination
B. Increasing their moisture content deliberately
C. Changing their orientation randomly
D. Removing all markings before transportation
