Behavior of Compacted Clayey Soils Mixed with Copper Slag

Abstract

As we all know that day by day the dumping  of wastes becomes a challenge for civil Engineers. We can’t  dump wastage at everywhere into the soil but after a lot of  research it has been concluded that we can mix the wastage  of various elements with the soil in a specified proportion in  order to enhance the geotechnical properties of soil. In this  thesis work we have taken copper slag and mix it with the soil  to stabilize it. We have replaced the soil by copper slag by  10%, 20%, 30% and 40% respectively. After proper sampling  we have done three tests on every sample such as CBR Test,  Optimum Moisture Content (OMC) & Maximum Dry  Density (MDD) Test and Unconfined Compression Test  (UC). After the testing we have observed that Optimum  Moisture Content decreases continuously with the  replacement of soil by copper slag while Maximum Dry  Density Increases continuously. Similarly, both soaked and  un-soaked CBR test values increase with the addition of  copper slag. Unconfined compression test increases rapidly  initially but after 20% replacement it increases gradually. The  result has been shown both numerically and graphically in  this thesis work.
