| Summary: | The geotechnical properties of soils containing high amounts of clay minerals can be altered through chemical stabilization, resulting in a material suitable for construction purposes. The primary objective of this investigation was to study the changes in the geotechnical properties, such as compression, permeability and shear strength characteristics in laterite soil induced by adding various percentages of Sodium Carbonate (NA2CO3). Based on the obtained data it found that the soda ash increased pH value of soil from 4.87 to 9.82 while increasing in shear stress and cohesion of soil. On the other hand, liquid limit growth by more admixing of soda ash whereas the maximum dry density experienced its peak by 10% soda ash of weight of soil. The results show natural laterite soil has coefficient permeability of 8.83E-5 cm/sec while results show reduction in permeability value in all tests by various percentages of treating soil by soda ash. |
