Effects on Index Properties of Black Cotton Soil by Alakali Content Sodium Hydroxide (NAoh)

Stabilization is a technique to improve Physico-chemical and geotechnical properties of soil so as to obtain desired characteristics of soil for any structural work, herein this research work NaOH is used as a stabilizing agent to stabilize the Black cotton soil collected from Jabalpur region. Ions Na+ and OH-interact with silica and alumina present in soil to chemically change its properties. The main Objective of this research work is to determine the effects of NaOH on mixing with black cotton soil used as a stabilizing material. NaOH is mixed in different concentration varying from 0 to 16%with soil and properties like consistency limit, Shrinkage Limit, and Swelling percentage are oberserved with the increasing concentration of NaOH, It can be concluded that some properties of Soil improved and some degraded.
