| Summary: | The
present study aimed at the use
of locally available pulverized fuel ash (PFA) from
Sejingkat
P
ower
Corporation (SPC
), Kuching, Sarawak, to improve the geotechnical
properties of soil. To achieve this, the soil samples were mixed with different
percentages
(i.e., 5, 10, 15 & 30%) of PFA contents. The amount of PFA added was on the basis of mass
replacement (i.e., Soil
-
PFA mixture with 30% of PFA means, 70% of Soil and 30% of PFA).
Standard Proctor test and California Bearing Ratio (CBR) test wer
e conducted to determine
the strength of the mixtures. The
compaction
results reveal that there is an increase in
maximum dry density with the increase of PFA, while decreasing in optimum moisture
content (OMC). The soaked CBR values for Soil
-
PFA mixtures
were found to increase
by
0.784
%
and 0.12%
with the increase of PFA content
of 15% and 30%, respectively
. The
improvement of engineering properties of soil indicates that PFA can be used as a soil
stabilizer and it would also provide an opportunity for the
utilization of an industrial waste. |
