Industrial advances in agriculture and chemical industries has to lead to release of variety of pollutants into the environment contaminated the soil. Soil being contaminated by anthropogenic sources such as leakage from waste containment facilities, accidental spills and industrial operations. In this project report the effect of Sulfuric (H2SO4), Nitric (HNO3) and Boric (H3BO3) acids on the strength characteristics of black cotton soil at varying percentage studied. Laboratory regent sulfuric, nitric and boric acids were used in concentration of 0, 2, 4, 6, 8, and 10 percents, the acid contamination of soil adversely affects the strength characteristics of soil. The strength characteristics of soil get altered when an acid compounds gets mixed with soil. Atterberg’s limits, compaction characteristics, CBR test and unconfined compressive strength tests have been carried out. The results are indicative that compaction characteristics, CBR test and unconfined compressive strength are altered due to acid contamination.
