| Summary: | Constructions on soft clay are often affected by stability and settlement problems.
Ground improvement methods have been used in many parts of the world to minimize
these problems. The aim of this research is to evaluate the engineering properties of
Batu Pahat Soft Clay (BPSC) mixed with three types of admixtures. This research
presents the stabilization of BPSC using admixtures lime, cement and natural sodium
bentonite at varying binder contents (5%, 10%, 15%, 20% and 25%). The basic soil
properties such as compaction, unconfined compression strength, California bearing
capacity and permeability testing methods were used to gauge the behavior and
performance of the stabilized soils. From the tests conducted, the researcher has found
that the addition of lime, cement and natural sodium bentonite decreased the
maximum dry density and increased the optimum moisture content. The tests
conducted gave some indication that the unconfined compressive strength increased
with the percentage of stabilizer and curing periods for cement treated sample
compared to lime and bentonite treated sample. It also showed that an increase in the
binder content and curing periods results in a reduction of the permeability of the
stabilized soils. The results of California Bearing Ratio (CBR) indicated that the
increase of curing periods and percentage of stabilizers led to an increase in the CBR
values for cement treated sample compared to lime and bentonite treated sample. |
