Influence of water content on the electrical resistivity of biocemented soils investigated through the shape of the water retention curve and considering chemical effects

Non-destructive tests, such as geophysical electrical resistivity can be useful to determine how Biocementation treatment in soils is distributed volume. However, affected not only by void ratio but also water content and the chemical nature of pore fluid. This paper presents an experimental investigation performed analyse changes on a sandy soil after biocementation using enzymes, considering content. Electrical measurements were carried out Wenner method retention curves untreated treated sands measured Water Dewpoint Potentiometer (WP4). The for wetting paths similar both soils, suction during drying with biocement was higher than that because elements fluid presence clogging pores. do allow conclude what extent affects conductivity electricity through soil, however are related even ions due treatment. Detailed study these parameters could help understand if this non-destructive technique used monitor progress volume soil.
