Measurement of danger of corrosion of concrete reinforcement - involves application of electrode to concrete and connection to steel reinforcement

摘要: A galvanic cell is produced in a test area between the reinforcement elements and concrete unit surface by application of an electrode on concrete, connection current supply to elements; constant d.c. applied it. The steel connected as anode potential distribution over measured against reference during period beginning shortly before application; this starts some 10 seconds connection, lasts one three minutes.
