RESULTS AND DISCUSSION The outcomes of the tests undertaken in this study are presented in this chapter. Free swell test, unconfined compression test, standard proctor test, and ATTERBERG limit test were used to investigate the behavior of black cotton soil and brick dust combination. The impact of compaction, water content, dry density, and optimal moisture for various percentages of brick dust were investigated. The proportion of brick dust in the mix variesfrom 5% to 15%.
