Standard Specification for
Lightweight Aggregates for Structural Concrete1
This standard is issued under the fixed designation C 330; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
1. Scope
1.1, This specification covers lightweight aggregates in¬tended for use in structural concrete in which prime consider¬ations are reducing the density while maintaining the compres-sive strength of the concrete. Procedures covered in this specification are not intended for job control of concrete.
1.2 The values stated in SI units are to be regarded as the
standard. The values shown in parentheses are for information
purposes only.
1.2.1 With regard to other units of measure, the values stated in inch-pound units are to be regarded as standard.
1.3 The text of this standard 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.
NOTE 1—This specification is regarded as adequate to ensure satisfac¬tory lightweight aggregates for most concrete. It is recognized that it may be either more or less restrictive than needed for some conditions and for special purposes, such as fire resistance, fill, and concrete constructions, the use of which is based on load tests rather than conventional design procedures.

3. Aggregate Types
3.1 Two general types of lightweight aggregates are covered
by this specification, as follows:
3.1.1 Aggregates prepared by expanding, pelletizing, or
sintering products such as blast-furnace slag, clay, diatomite,
fly ash, shale, or slate, and
3.1.2 Aggregates prepared by processing natural materials,
such as pumice, scoria, or tuff.
3.2 The aggregates shall be composed predominately of
lightweight-cellular and granular inorganic material.
4. Chemical Composition
4.1 Lightweight aggregates shall not contain excessive amounts of deleterious substances, as determined by the following limits:

4.1.1 Organic Impurities (Test Method C 40)—Lightweight
aggregates that, upon being subjected to test for organic
impurities, produce a color darker than the standard shall be
rejected, unless it is demonstrated that the discoloration is due
to small quantities of materials not harmful to the concrete.
4.1.2 Staining (Test Method C 641)—An aggregate produc¬
ing a stain index of 60 or higher shall be rejected when the
deposited stain is found upon chemical analysis to contain an
iron content, expressed as Fe2O3 equal to or greater than 1.5
mg/200 g of sample.
