RS ASTM C331/C331M-23
Standard Specification for Lightweight Aggregates for Concrete Masonry Units
Abstract

1.1 This specification covers lightweight aggregates in-
tended for use in concrete masonry units when a prime
consideration is to reduce the density of the units.
1.2 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. Some values have only SI units because the
inch-pound equivalents are not used in practice.
NOTE 1—Sieve size is identified by its standard designation in Speci-
fication E11. The alternative designation given in parentheses is for
information only and does not represent a different standard sieve size.
1.3 The text of this specification references notes and
footnotes which provide explanatory material. These notes and
footnotes (excluding those in tables and figures) shall not be
considered as requirements of the standard.
