Concrete Electrical Resistivity as a Durability and Service Life Parameter for Reinforced Concrete Structures
Electrical resistivity becomes one of the main non-destructive techniques in the evaluation of the service life and durability of reinforced concrete structures, considering chloride penetrability and/or the probability of reinforcement corrosion, being pointed out by different standard and studies in literature. Due to the use of a non-destructive methodology of easy operation, reliable, with expeditious results and low cost, it becomes an important tool for decision making by managers responsible for plans and strategies for concrete structures maintenance. Thus, this chapter presents definitions and aspects of electrical resistivity in concrete, test procedures and interpretation of results and, finally, the parameters that most influence concrete resistivity are discussed.
