Correct Answers ✅ASTM C173 / C173M-07
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. - Correct Answers ✅Molds
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. - Correct Answers ✅Cylindrical Specimens
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. - Correct Answers ✅Beam Specimens
