| Summary: | The
uses
for
carbon
fiber
reinforced
concrete
(CFRC)
has
expanding
in
recent
times.
While
the
world
is
turning
to
cleaner
and
greener
options
for
the
power
supply,
the
thermoelectric
properties
of
CFRC
may
prove
to
play
a
significant
role
in
the
near
future.
The
processes
of
casting
CFRC
as
well
as
carbon
nanotube
reinforced
concrete
(CNTRC)
samples
is
examined
in
detail,
while
limitations
and
problems
observed
are
also
highlighted.
The
2-‐probe
testing
phase
in
which
the
Seeback
coefficients
of
the
samples
are
determined
is
also
examined
in
detail.
Lower
concentrations
of
carbon
fibers
tend
to
produce
more
unstable
readings.
In
this
report,
the
linearity
of
the
curves
with
respect
to
the
Seeback
coefficient
can
be
seen
to
improve,
from
0.4%
to
2.0%,
while
lower
concentrations
tend
to
reflect
a
semi-‐conductor
like
behaviour
with
relatively
erratic
results.
CNTRC
samples,
on
the
other
hand,
produced
inconclusive
results,
and
reflected
similar
behaviour
to
the
0%
carbon
fiber
concentration
sample.
4-‐probe
resistivity
testing
methods
have
been
used
to
determine
the
resistivity,
but
the
results
have
not
proved
to
be
reliable.
The
use
carbon
fiber
or
carbon
nanotube
reinforced
concrete
may
yet
play
a
significant
role
in
creating
another
source
of
power
for
mankind,
and
such
research
may
well
open
the
world
to
new
possibilities. |
