EFFECT ON CBR AND UCS VALUE OF SOIL WITH ADDITION OF BRICK DUST AND WASTE REFRACTORY MATERIAL by Sukhpreet Singh
Abstract
To start any project it is necessary to know which kind of soil is exist in particular area of project. Natural soil is foundation of any structure as it lastly rest on soil and load carried by soil below the foundation of any structure. Soil present in that area should has good bearing capacity and it is stable or need to stabilize. Sandy or silty sandy soils are good for construction purposes. Clayey or silty clayey soils need to stabilize and it may be effect the cost of the project as well as time of project. Soil stabilization is done by various methods such as mechanical, cement, lime, chemical stabilization. Now-a-days different kind of waste material such as brick dust, fly ash, saw ash and stone dust are used for soil stabilization. Keeping view of this, waste material like brick dust and refractory material are used in this study to enhance the geotechnical properties of soil. Unconfined compressive strength test (UCS) and California bearing ratio test (CBR) were carried out to see improvement in the soil properties. The results of both tests showed significant increase after addition of brick dust and waste refractory material. The optimum quantity of brick dust is find out is 30% by CBR test The optimum mix of soil + brick dust + waste refractory material is 61 + 30 + 9. This will give alternate to the traditional stabilizer and also decrease the overall cost of the project
