From the result presented in the above tables and figures, it show that the maximum dry density decreases as the rate of contamination increases and the optimum moisture content increase as the rate of contamination increases.
This may be attributed to reduction of ion oxide content as a result of ion exchange that might occur between the sodium ion and iron ion. It is confirmed that the coating of iron oxide on the surface of the aggregates make the particles into clusters. The soil particles in their natural condition are held together because of the presence of free ion oxide which on drying tends to coagulate the particle into strong cluster. Therefore, since the contaminated soil sample lack iron oxide to fill the void between the grains, the maximum dry density will decrease And optimum moisture content will increase.

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONE1.0 INTRODUCTIONSoil is the cheapest and the most widely used material in civil engineering project as foundation material either in its natural or improved form. It is highly heterogeneous and an isotopic in nature and existing with different engineering properties which can be influenced to some extend by the presence of sodium salts under the influences of water (Olawale, 2013). ...
