Electrical Conductivity Of Limestone

geo-electrical characterisation for co 2 sequestration in,the laboratory experiment was designed to monitor the co 2 level in porous media such as silica sand, limestone and basalt. the characteristics of the samples used are described in table 1.the relationship between geo-electrical properties, i.e., bulk electrical conductivity and bulk dielectric permittivity (σ b and ε b) and water saturation (s w) makes it possible to monitor the amount of.is limestone electrically conductive,most aggregates e.g., limestone used in concrete, with electrical resistivity ranges between 3102 and 1.5103 -m, are essentially not conductive. conductive concrete may be defined as a cement-based admixture, which contains a certain amount of electrically conductive components to attain a stable and relatively high electrical conductivity..
