ACI CONCRETE FIELD TESTING TECHNICIAN
GRADE I EXAM SCRIPT 2026 QUESTIONS
WITH ANSWERS GRADED A+
◉ASTM C1064 /C1064M-05 ANSWER: - Standard Test Method for
Temperature of Freshly Mixed Hydraulic-Cement Concrete
◉ASTM C172 -07 ANSWER: - Standard Practice For Sampling Freshly
Mixed Concrete From Different Containers Used In The Production or
Transportation Of Concrete.
◉ASTM C143 / C143M-05a ANSWER: - Standard Test Method for
Slump of Hydraulic-Cement Concrete Both In Laboratory And In The
Field
◉ASTM C138 / C138M-07 ANSWER: - Standard Test Method for
Density (Unit Weight), Yield, and Air Content (Gravimetric) of
Concrete
◉ASTM C231 -04 ANSWER: - Standard Test Method for Air Content
of Freshly Mixed Concrete by Pressure Method
◉ASTM C173 / C173M-07 ANSWER: - Standard Test Method For Air
Content of Freshly Mixed Concrete Containing Any Type Of Aggregate,
Whether It Be Dense, Cellular, or Lightweight by Volumetric Method
, ◉Molds ANSWER: - Mold for specimens shall be made of steel, cast
iron, or other nonabsorbent material, nonreactive with concrete. Molds
shall be watertight and hold their dimensions and shape under all
conditions of use.
◉Cylindrical Specimens ANSWER: - Compressive or Splitting Tensile
Strength Specimens shall be cylinders cast and allowed to set in an
upright position. The length shall be twice the diameter (4 X 8in or 6 X
12 in). The cylinder daimeter shall be at least 3 times the nominal
maximum size of the coarse aggregate. When the nominal maximum
size of the coarse aggregate exceeds 2 inches the concrete sample shall
be treated by wet sieving through a 2 inch sieve.
◉Beam Specimens ANSWER: - Flexural strength specimens shall be
beams of concrete cast and hardened in the horizontal position. The
length shall be at least 2 inch greater than three times the depth as tested.
The ratio of width to depth as molded shall not exceed 1.5. The standard
beam shall be 6 by 6 inches in cross section, and shall be used for
concrete with nominal maximum size coarse aggregate up to 2 inches.
When the nominal maximum size of the coarse aggregate exceeds 2
inches, the smaller cross sectional dimension of the beam shall be at
least three times the nominal maximum size of the coarse aggregate.
◉Tamping Rod ANSWER: - A round, straight steel rod having the
tamping end or both ends rounded to a hemispherical tip of the same
diameter as the rod.
Rod Dimensions are based off of the diameter of Cylinder or Width of
Beam.
