Stone dust is a kind of solid waste material that is generated from stone crushing industry which is abundantly
available. It is estimated that each crusher unit produce 15%-20% stone dust. Disposal of such wastes creates lots of
geo-environmental problems such as landfill disposal problems, health and environmental hazards. One of the best way
to eliminate these problems is to make use such waste. Fly ash is a waste by product from thermal power plants, and
consuming thousands hectares of precious land for its disposal and also causing severe health and environmental
hazards. This paper presents the results of an experimental program undertaken to investigate the effect of stone dust &
fly ash combined in equal percentages on physical properties soil and to study effect of this admixture on the
geotechnical properties such as index properties including Liquid Limit, Plastic Limit, Compaction characteristics and
CBR value.
