THE EFFECT OF ADDED NICKEL SLAG TO COMPRESSION AND SHEAR STRENGTH ON LATERITE SOIL SOUTH KALIMANTAN

Laterite soil is an embankment that often used because it easy to find and widely found in South Kalimantan. However, this land has many shortcomings be as soil. This the lateritic a clay content high Plasticity Index (PI) value. So quality still questionable landfill. To overcome this, necessary improve or stabilize In study, was stabilized by addition of slag nickel study aims determine physical characteristics laterite after being given mixture addition, also effect percentage on primary consolidation (Sc) As well knowing parameters shear strength form cohesion (c) angle (f). Consolidation specimens were made with 90% optimum moisture content. The variations 0%, 5%, 10%, 15%, 20% weight used. Based results data analysis, each sample variation can reduce plasticity index value affects settlement soil, for experiences decreases increase slag. Meanwhile (φ) increases slag.Keywords: slag, index,
