| Summary: |
Silica produced from rice husk ashes have investigated successfully as a
pozzolanic material in soil stabilization. However, rice husk ash cannot be used
solely since the materials lack in calcium element. As a result, rice husk ash shall
be mixed with other cementitious materials such as lime and cement to have a solid
chemical reaction in stabilization process. The main objective of this study focused
on bearing capacity of the stabilized clayey subgrade with lime-rice husk ash and
fibers. The main laboratory test shall be compaction and CBR tests. The
investigation results revealed that the inclusion of lime-rice husk ash-fiber into the
soil decreased MDD and OMC. On the other hand, stabilization and reinforcement
with lime-rice husk ash and fibers waste improved significantly the CBR values. |
