Corrosion of subsurface steel structures is very critical issue especially in moisture subsoil. The use ofphysiochemical properties such as pH, salts concentration, electrical resistivity is very common to quantify corrosivenature of subsoil. However, the laboratory measurements of these parameters are quite difficult due to time and budgetconstrai...

... and (BH5). The depth of each bores hole differs from each other particularly depth fluctuates from 30 meters to 50 meters. Near the ground level the depth almost up to 2 m, the nature of soil was low in plasticity, soft to stiff, silty clay, whereas in lower part constitutes the dense, silty to poorly graded sand shown in soil profile A to B (Fig. 4). Each bore hole describes the level of water in each borehole profile. During grain size analysis gravel percentage varies from 0.0 % to 3.8 %, sand particles fall in 0.6 % to 89.4 % and fine particles of soil vary from 0.7 % to 99.1 %. Three boreholes (BH6), (BH7) and (BH8) lie in the soil profile C to D (Fig 5). The depth varies from ...
