Abstract: Fly ash is considered as a waste raw material which is generated from gases that comes from coal furnaces, mainly of a thermal power plant. The demand of electricity supply has boosted up in this era due to increase in urban and industrial development. This advancement has also increase the counting of electricity producing plants i.e. Thermal power plants, which results in more coal burning and the amount of residue (fly ash) also run-up. Disposal of Fly ash is a big global issue today, because of its fineness and ultra-light weight it tends to mix with the natural clean air and create many respiratory problems to living beings. Sea Shells are natural coastal waste found on the coastline. They are the hardened skeleton of mollusks. Before using the Fly ash as an additive material in soil stabilization in various engineering projects, its engineering properties need to be investigated and improved using other materials as an admixture. Sea Shell powder derived hard naturally available Sea Shell which is rich in calcium is used with Fly ash as an admixture to improve its engineering properties. The clayey soil used in this study was procured from Bholath town in district Kapurthala in the state of Punjab. Fly ash was obtained from local batching plant situated in Alawalpur in Jalandhar and Sea Shells in its natural form were obtained from a Chennai based dealer. The aim of the present work is to find the optimum amount of Fly Ash and Sea Shell powder required to improve the engineering properties (CBR AND UCS) of Clayey soil. It was noted that an increment of 176% in CBR and 30% in UCS of clayey soil may be achieved if Fly ash and Sea Shell powder were mixed in clayey soil.
