Density, load and fly ash effect on stabilization of high plasticity soil with lime

The reuse recycling materials or industrial waste with aims to reduce pollution and environmental pollution, strongly supports concept of green building. Fly Ash is result combustion pulverized system coal at the PLTU Tenayan, no longer included in B3 category. usage as building material, mine restoration, roads this decade, replace cement lime. fly ash composition mixed lime for sub-base, will applied on high plasticity soils. A fix-mixture soil 5%, up 30% mixture. samples test was made Optimum Moisture Content, density values around Maximum Dry Density i.e. under compacted (under MDD) over (above MDD). Consolidated testing performed without curing. Changes load are represented by increment ratio (LIR). selected LIR value 1.0; 1,5; 2.0. results showed that higher density, volume void lower. compression index same all values, if structure has not destroyed. fatigue yet. In crushed/broken structures, compressibility decreased sharply. Curing successfully soil. strength decrease when reacting water, so burdened, decreases drastically. formation strong molecular bonds between takes time. So, sample curing 28 days better than levels also affects optimum combination occurs a content 25%.
