The effects of potassium permanganate on the geotechnical properties of soils

In Nigeria, potassium permanganate (KMnO4) is used as a chemical oxidant in the removal of hydrocarbons from polluted soils and groundwater, but there no information on effects KMnO4 geotechnical properties soil. this study, was added separately to lateritic soil kaolin at concentrations 0 %, 2 5% 10 % by weight dry Each mixes then subjected grain size analysis, Atterberg limits, specific gravity, compaction, California bearing ratio (CBR) tests. The results showed that an increase generally decreased values maximum density (MDD), optimum moisture content (OMC) both unsoaked soaked CBR for soils. conclusion, study shows although excellent remediation contaminated sites, it reduces therefore should not be alone (without use other additives) stabilisation.
