Analysis of Unconfined Compressive Strength in Clay Mixed with Sand

Clay soils are that have high shrinkage potential and good carrying capacity in water unsaturated conditions but poor water-saturated conditions. soil has a low capacity, so to increase the of it needs be stabilized by using an added material which is sand. Land used for 100% disturbed soil, 95% + 5% sand, 90% 10% 85% 15% with curing time 3,7,14, 28 days. The mixture was tested aunconfined compressive strength test instrument SNI 03-6887-2002 method. results unconfined showed maximum occurred addition sand at age days curing, reached 1,194 kg/cm2. But increased when reaching 1,348 kg / cm2. Based on testing more amount added, higher value obtained.
