Recently, an ore of stone obtained from quarry lose its about 60% such as the muck and the stone-dust during the process of making the architectural block, the crushed aggregate and so on. A part of the muck is only reutilized for the crushed aggregate as road pavement materials, while the most of the muck in the shape of powder is mixed with water and then it is deposited in
a sludge tank. The much in the shape of powder is called the stone-dust. If the stone-dust is discharged and sprayed, an ecosystem will have terrible damage because the seepage of surface water, the flow of ground water and the movement of air are not occurred smoothly by packing the void of soils. Therefore, the establishment of an efficient recycling plan are necessary through the improvement of engineering properties of the stone-dust. This study is to investigate the possibility of recycle and improvement for the Granite powder is sampled from quarry in Korea. The various strength tests are performed by use of the mixed soils with the Granite powder content ratio. As the result of various strength tests, the recycle possibility of the Granite powder is analyzed as subbase layer materials of the construction.
