Unconsolidated Undrained Behavior of stabilized clayey soil with lime and industrial sludges

Industrial waste generating has reached up to millions of tons yearly. One way to solve the problem of this large accumulating amount of waste could be to return back to soil. Thus, finding a way for use industrial waste could be a quest for soil improvement studies. Steel and copper sludge are from the main wastes inmetal industrials. Industrial sludge in certain pozzolanic react with soil and water possess cementitious properties compounds. A pozzolan is a siliceous or siliceous and aluminous material which, in itself, possesses little or no cementitious value but which will, in finely divided form and in the presence of water,react chemically with calcium hydroxide at ordinary temperature to form compounds possessing cementitiousproperties. This study illustrates the utilization of lime, steel and copper sludge in stabilization of high plasticity clayey soil. Various replacement ratio of lime and sludge are tested in various curing time. The results gained unconsolidated undrained triaxial test show enormous changes in soil mechanical behavior of soil.
