Stabilization of Black Cotton Soil Using Blast Furnace Slag - A review

Ashutosh Rawat, Ajay Kumar Pandagare


Soil stabilization may be defined as the alteration of the properties of an existing soil to meet specified engineering requirements. The main properties that may require to be altered by stabilization are strength, volume stability, durability and permeability. In India, the black cotton soil covers an area of about 0.8 million sq. km. which is about 20% of the total land area. It is considered as problematic soil due to detrimental volume changes with variation in moisture content. When it comes in contact with water it shows immense swelling whereas it shrinks with the decrease in water content and develops cracks on drying. Now-a-days the utilization of waste products with soil has gained attention due to the shortage of suitable soil and increasing problems of industrial waste management.
