EXPERIMENTAL STUDY ON POND ASH REINFORCED WITH GEOSYNTHETIC

Abstract

Pond ashzknown as a cohesionlesszmaterial having veryzless plasticity andzhas possiblity tozbe utilizezas a fill material in Geotechnicalzstructures like retainingzwalls, embankmentz, below pavement, structuralzland filling etc.zHowever according tozthe literature reviewzcompacted pondzash, which provideszsimilar strain that ofzthe earth material similarlyzgraded. in dry and moderatelyzwet conditions, afterzthe saturation it loseszits shearzstrength significantly . So in mostzof the designzit is recommended thatzprovisions should made. tozkeep the waterzaway from thezcompacted. pond ashzfills by given that a layerzof compacted soilzto cover it.zHowever the strengthzof the compacted pond ashzfills can be recollectedzpartially by reinforcingzit in a properzmanner. Soilzreinforcement techniqueais one of allzthe morezstandard techniques used for increasingzthe load carryingzcapacity of poorzsoils. Metalzstrips, syntheticzgeotextiles, geogridzsheets, natural geotextiles at randomlyzdistributed, synthetic and naturalzfibers are used effectivelyzas reinforcing materials tozsoil. Further, the reinforcement of soilzcauses important improvement inzphysical property, shearzstrength, different zproperties, bearing capacity andzeconomy. This canzbe a relatively easyztechnique for groundzimprovement and has tremendouszpotential as a cost effectivezsolution to several Geotechnicalzproblems.
