INTRODUCTION
ASTM
C
311
essentially
relies
on
ASTM
C
114
for
methods
for
the
determination
of
chemical
composition
of
coal
fly
ash,
but
the
latter
document
does
not
purport
to
be
applicable
to
materials
other
than
hydraulic
cements,
and
therefore
its
estimates
of
precision
and
bias
are
not
applicable
to
coal
fly
ash.
The
purpose
of
this
report
is
to
report
the
results
of
an
interlaboratory
study
conducted
in
1987-89
for
the
purposes
of
developing
these
estimates.
Seven
laboratories
participated
in
the
study:
Ash
Grove
Cement
Co.;
Cal-Mat
Co.;
Dundee
Cement
Co.;
General
Portland,
Inc.;
Resource
Materials
Testing,
Luc;
Riverside
Cement
Co.;
Waterways
Experiment
Station.
MATERIALS
AND
METHODS
National
Institute

Standards
and

Standard
Reference

(SRM's)
coal
fly
ash
samples
2689,
2690,
2691,
and
1633a
were
used
in
the
program.
Participants
were
instructed
to
complete
analyses
according
to
ASTM
C
311-87.
These
methods
are
basically
ASTM
C
114
reference
methods
for
the
chemical
analysis
of
hydraulic
cements
for
which
insoluble
residues
exceed
1%.
The
C
114
method
for
determination
of
Fe^
has
been
changed
since
this
interlaboratory
work
was
done.
Therefore,
precision
and
bias
estimates
for
this
method,,
which
were
developed
and
reported
by
Richter
and
Poole
(1992),
are
substituted
for
the
results
obtained
in
the
interlaboratory
study.
RESULTS
Results
reported
by
each
laboratory
are
summarized
in
Table

along
with
simple

are
not
related
to
the

in
which
laboratories
were

above.
All
data
and
descriptive
statistics
are
reported
to
two
decimal
places.
There
was
no
substantial
evidence
that
any
data
needed
to
be
removed
because
of
variances
that
were
too
high
of
too
low,
as
described
in
C
802.
There
were

instances
in
which
a
particular
set
of

摘要：

ASTM RR-C09-1008 1994 是一项由美国材料与试验协会（ASTM）发布的耐火材料标准规范，主要涵盖特定耐火制品的分类、性能要求与测试方法。该标准旨在为工业高温应用提供统一的质量基准，确保材料在极端热环境下的稳定性、耐久性与安全性。其中包含了化学成分、物理强度、热膨胀系数及抗热震性等关键指标的界定，适用于钢铁、玻璃、陶瓷及石化等行业的耐火砖、浇注料与绝缘材料。研究人员与工程师可依据此文档进行材料选择、质量验收及工艺优化，从而提升设备运行效率并降低维护风险。该标准的制定基于1994年
