The spatial extent of black cotton soil in India is more with low bearing capacity and high settlements. These soils have to be stabilized to improve bearing capacity and to reduce settlements of the structures to be constructed on them. Huge amount of research is carried in stabilizing black cotton soils with various stabilizers (lime, cement, phosphogypsum, rice husk ash, groundnut shell ash, waste saw dust ash and other materials) showed improvement in the properties of the soil. Recently Bio-Enzymes also used as stabilizers. This paper is an attempt to study the effect of Sulphuric acid and Sodium Hydroxide on black cotton soils when mixed at pH levels of H2SO4: 1, 3, 5 and NaOH: 9, 11, and 13 with the help o
