RS ASTM C138/C138M-24a
Standard Test Method for Density (Unit Weight), Yield, and Air Content (Gravimetric) of Concrete

Abstract

1.1 This test method covers determination of the density
(see Note 1) of freshly mixed concrete and gives formulas for
calculating the yield, cement content, and air content of the
concrete. Yield is defined as the volume of concrete produced
from a mixture of known quantities of the component materi-
als.
1.2 The text of this test method refers to notes and footnotes
that provide explanatory material. These notes and footnotes
(excluding those in tables and figures) shall not be considered
as requirements of this test method.
1.3 The values stated in either SI units or inch-pound units
are to be regarded separately as standard. The values stated in
each system may not be exact equivalents; therefore, each
system shall be used independently of the other. Combining
values from the two systems may result in non-conformance
with the standard.
