PENGARUH PENAMBAHAN KAPUR TERHADAP KEKUATAN DAN PENGEMBANGAN (SWELLING) PADA TANAH LEMPUNG EKSPANSIF BOJONEGORO
ABSTRACT: Expansive clay soil
has a low bearing capacity on condition that the high water level, the nature
and development of shrinkage (swelling) were large and high plasticity. One
method of stabilization of the soil used in an attempt to improve the quality
of the soil is poor, among others, chemical stabilization. Chemical
stabilization is done by adding stabilizing agents on the basis of land that
will be upgraded. Stabilizing agents used in this study is lime (lime). In this
study, the object being observed is, without stabilization of expansive clay
and expansive clay with stabilization. Soil stabilized with lime content of 6%,
8%, 9% and 10% of the dry weight of the soil. This study involved testing the
physical properties of the analysis granules, Specific Gravity, Atterberg
Limit, and compaction, as well as testing the mechanical properties of soil
CBR, Swelling, and triaxial. From the results of the test specimen, the native
land of the inorganic clay with high plasticity, expands the potential is very
high and has a value of current activity. The value of the liquid limit (LL)
and plasticity index (PI) decreased with increasing levels of lime, while the
value of plastic limit (PL) and the shrinkage limit (SL) increased with increasing
lime content. The increase in the value of CBR soaked and unsoaked highest in
the percentage of lime addition of 8% and more and more levels of lime are
added, the smaller the swelling that occurs. Relationship stress and strain
that occurs on lime content of 8%.
