PENGARUH TRAS TERHADAP PARAMETER KUAT GESER TANAH LEMPUNG
ABSTRACT: The previous
study result showed
that soil from
Tanon Sragen is
categorized as water-sensitive inorganic clay which has high
plasticity index and contain montmorillonite mineral dominantly. This kind of soil is
not reliable for
construction foundation. .Therefore,
its physic and
mechanic characteristic should be improved using stabilization method
in order to make the soil more reliable for construction foundation. The method
of improvement is conducted by mixing the soil with stabilization material by
adding tras percentage, i.e. 0%; 2,5%; 5%; 7,5%; and 10%, with 3-days
treatment. Changes in physic and mechanic characteristics of mixed soil and
tras can be seen by conducting consistency limit test, gradation test, specific
gravity test, and unconsolidated-undrained
(UU) triaxial test. The
result shows that
tras adding with
3-days treatment can improve the soil physic and mechanic
characteristic, such as reduce soil plasticity, increase value,
and reduce soil cohesiveness value (c).
