骨料组合潜性碱质反应性标准测试方法 (灰浆棒方法) 1
本标准按照标号C 227制定; 在修正情况下，标号后表明原先采纳的年度或，先前修正的年度。括号内数字表明上次重新评价的年度。上标ε (e)表明最后修正或重新评价编辑变化。
本标准经国防部的代办处批准使用。
1. 范围
1.1本测试方法用于在测试规定的情况下，通过测量存贮期间组合包含灰浆棒增量(或减退的)的长度，确定关于氢氧离子与碱的膨胀反应 (钠和钾)骨料组合的极化率。
1.2参加膨胀反应的碱通常从水泥中获得; 在某些情况下，他们也可以从外部来源获得或从混凝土的其它组成部分中获得。可以确认聚集体碱反应性的二个类型：(1) 硅质岩石、矿物和自然或人造玻璃与碱硅土反应 (2) 某些方解石白云岩中的白云岩和含白云石的石灰石的碱碳酸盐反应(参见标准C294)。不推荐该方法作为探测后者反应的手段，因为在灰浆棒测试碱碳酸盐反应导致的扩张 (参见测试方法C 586)比碱硅土反应生产的一般要少，组合在使用中有同等的恶性影响。
1.3在SI中陈述的数值视为标准数值。括号内显示的非SI数值只作提供的参考信息。
1.4本标准不表述所有相关安全陈述，如果有，陈述只与用途相关。本标准的用户有责任建立适当的安全卫生实践，并且在使用之前确定适当的安全预防措施。

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.
