摘要：In sites with high soil resistivity such as deserts and mountainous terrains, designing and
installing an effective grounding system is a challenging task. Therefore introduction of
Bentonite into concrete mix of Ufer grounding at various proportions was done in a previous
study and its steady state ground resistance performance was investigated. In that study, itwas
found that 30% Bentonite-concrete mix is the optimum compound which yields the lowest
average ground resistance with the least fluctuation as well. Subsequent study at site with high
soil resistivity found that its performance is among the best compared with several conventional
setups. In current work, such mix and the standard concrete mix were installed in five sites with
varying soil resistivity to determine the correlation between ground resistance and localized soil
resistivity. These correlations serve as a guide for future applications by engineers in designing
grounding system using the best mix.
