PEMANFAATAN ABU SEKAM PADI SEBAGAI PENGGANTI SEMEN PADA METODA STABILISASI TANAH SEMEN
ABSTRACT: Sub base course and
base course are the layers under the surface course. Generally, materials ofsub
base course or base course are fine aggregates and coarse aggregates. But some
locations infield, sometimes can not be found the aggregates to use as the
material construction. Portlandcement is always used as the additive material
in soil stabilization method, but cost of portlandcement is very high. One of
the solution is used mixture of rice husk ash and portland cement asthe
additive material to stabilized of soils. The result of research, showed that
mixing of rice huskash material and portland cement can be able to increase of
soil plasticity properties and bearingcapacity and shear strength of soils.
Based on testing of bearing capacity at 9% prosentage of ricehusk ash material
and portland cement, with curring time in 28 days, can be recommended thatsoil
stabilization be used as base course in pavement structure of highway
engineering, whereCBR Laboratory value is 120% in unsoked CBR and 102% in
soaked CBR.
