PERBAIKAN TANAH PROBLEMATIK LEMPUNG LUNAK DENGAN METODE STABILISASI KIMIAWI DITINJAU DARI NILAI KADAR AIR DAN INDEKS PLASTISITAS

<p>Soft clay soils generally have unfavorable characteristics or properties, when used as a basis for construction. The of soft soil are having high compressibility, low carrying capacity, permeability value, being cohesive and level activity. One form effort to improve the soil's bad properties is carry out stabilization. Stabilization an activity mixing with certain materials, expected react soil, so that become better. methodology applied in this study chemical stabilization, mineral materials marble ash waste 4 different types variants. Based on test results, there was decrease value water content plasticity index (PI) 44.94% variant 3 (20% waste) compared original soil. It estimated reaction from namely absorption excess contained voids filled waste, adhesion between particles becomes better.</p>
