Abstract

Expansive soils have low soil bearing capacity so that's causes often problems in buildings. One ways to repair soil bearing capacity is improve the strength of original soil with chemical stabilization methods using slag and fly ash. The research goals were to find out the effect of adding slag and fly ash with reference to unconfined compressive strength value and physical properties of the soil before and after stabilizing with slag (10%, 20% and 30%) and fly ash (20%) and to know classification soil on jalan Kadusentar, Pandeglang District - Banten based on USCS classification. The results of this study obtained original soil types including the MH category is non-organic clay with high plasticity. The UCT value of original soil was 1,407 kg/cm2 . Addition of slag and fly ash increased the value of unconfined compressive strength and can improve the physical properties of the soil by decreasing the value soil plasticity index. The maximum UCT value is the percentage of 20% fly ash and 10% slag of 8,393 kg/cm2 including hard consistency with unconfined compressive strength values greater than 4 kg /cm2 with curing time for 14 days.
