  • Electrical Resistivity of Concrete for Durability ...

    Degradation processes in reinforced concrete structures that affect durability are partially controlled by transport of aggressive ions through the concrete microstructure. Ions are charged and the ability of concrete to hold out against transfer of ions greatly relies on its electrical resistivity. Hence, a connection could be expected between electrical resistivity of concrete …

  • [PDF] Development of Concrete Water Absorption Testing …

    Concrete durability can be evaluated by a number of properties - such as water absorption and chloride diffusion. Each of these properties can be measured using Standardized methods. Water absorption can be linked to porosity and therefore to eventual deterioration. Tests based on absorption have the potential to be simple and rapid tests for placed concrete.
