Determination of the effectiveness of saw dust ash in improving the geotechnical quality of expansive soils :

Abstract

Soil is sediment or other unconsolidated accumulation of solid particles produced by physical and/or chemical disintegration of rock. It maybe organic, or inorganic material. Soil stabilization is one of the common and effective methods of improving the geotechnical quality of engineering soils Lime and sawdust are 'common examples of soil stabilizers, Soil used as foundation material and sub grade material should be strong enough to bear the load. The soils which are expansive in nature tends to swell in presence of moisture and shrink in dry condition this undesirable properties of expansive soil cause damage to structures. The application of industrial waste such as fly ash and saw dust ash or the combination of them often results in transformation of stability of soil. Some, studies have been carried out on geotechnical properties of laterite soil using stabilizers.
