Construction on soft soil is one of the most challenging situations faced
by geotechnical engineers. The heterogeneous and complex nature of soil,
especially those containing organic clay, often makes it impossible for the
construction specification to be addressed properly. Generally, clay exhibits
low strength, high compressibility, and strength reduction when subjected to
mechanical disturbance. This means that construction on clay soil is vulnerable
to bearing capacity failure induced by low inherent shear strength. All these
properties can be improved by the effective stabilization of soil. This study
analyzed the effectiveness of incorporating salt-lime mixtures at various
dosages in improving the strength increment of the soil. The results indicate
that among different combinations of salt and lime, the best performance in terms of strength increase was achieved by adding
10% NaCl with 3% lime in the soil. The outcome of this study focuses on
enhancing the ultimate strength of soil and its implementation in the
field of foundation engineering.
