The usage of waste material for stabilizing black cotton soil has been a sustainable interest. Kota stone slurry is a waste
from kota stone and fly ash is a waste from industries containing high amount of sodium and magnesium, was used as a soil
stabilizer for blac cotton soil improvement in this study. This research investigated the effects of sizes and percentages of kota
stone slurry mix and fly ash on the physical and strength properties, which included particle size distribution, Atterberg limits,
compaction, and unconfined compressive strength (UCS) of blac cotton soil.
