Experimental Study of Soil Stabilization by Partial Replacement of Fly Ash
Keywords:
Soil, Soil stabilization, Plasticity index, Workability, Fly ash, Volumetric indexAbstract
Expansive soil is clay that is prone to large volume changes. They are hard when dry but lose all strength when in wet state. Due to this property expansive soil pose problems for construction of infrastructural projects because due to volume changes there are damages to underlying structures. One of the methods for improvement of engineering property of expansive soil is by soil stabilization. Soil stabilization is a physical, chemical, biological method of changing an expansive soil to meet an engineering property. One of the methods of soil stabilization is by adding fly ash. Addition of fly ash results in decrease of plasticity of expansive soil and increase in workability. The present paper describes the study in improvement of expansive soil by adding fly ash in different proportions.
