| description | Soft soil improvement and stabilization has been widely practised for a long
time by mixing admixtures such as lime
,
cement and pond ash
to increase the
strength of the soil.
Different
types of admixtures were also used as
stabilizers to
improve the stiffness and strength of a clay soil. As for this study, the objective is to
analyze the improvement in local clay soil
when
being stabilized
by using fly ash
from the local coal plant.
Tests were first made to study the characteristics of the clay
soil. Then s
amples are prepared carefully to prevent inconsistencies between them
since the
outcome of each tests
must be related to each other in o
rder to produce a
significant
results.
Standard Proctor Test and Unconfined Compression Strength
(UCS) Test
are the main tests
used
in this study.
From the analyzed data, there is a
significant increase in strength when the clay
sample were mixed with fly
ash
and the
trend continues until the addition of 20
percent
fly ash to the sample.
The sample
containing 20
percent
fly ash tends to sustain more loads during the compression
tests. The strength of each samples increased until the seventh day of curing, before
gradually decreasing. However, the strength of the samples regained after the
fourteenth day.
As a conclusion
, local clay can also be stabilized or improved by
using fly ash, and this may become as a starting step for future assessments that
could lead to more soil improvement for ground soil in Malaysia. |
