Giatec RCON™ is an advanced tool for the electrical resistivity measurement of concrete using uniaxial method. RCON™ employs AC impedance technique for the accurate and fast readings that can be continuously obtained using its customizable and user-friendly operating software for various concrete materials. The electrical resistivity of concrete can be simply related to their pore network characteristics such as pore size and their connectivity, moisture content in the pores and pore solution chemistry. In concrete materials, the electrical resistivity has been correlated well with important durability parameters such as permeability and diffusivity.
In addition, this non-destructive test can be easily conducted on fresh or hardened concrete specimens at different ages or various stages of hydration in order to study workability, setting and durability performance of concrete. The electrical resistivity method has also been applied to investigate corrosion of rebar in concrete, creep, aggregate segregation and freeze and thaw of concrete since they affect the pore network properties.
