The investigation was carried out in order to monitor the continuous behaviour of concretes containing fly ash in a chloride exposure regime. Chloride penetration was simulated by subjecting samples to cyclic loading with salt solution and drying or to freeze-thaw cycles in presence of chloride salt. The results of long-term monitoring of electrical resistivity changes were confronted with the results of chloride penetration resistance of concrete using rapid test (RCMT). The resistivity monitoring was conducted during 12 months and the resistance to chloride penetration by means of rapid test was determined after 28, 90 and 180 days of curing. Based on the test results, the beneficial effects of cement type, fly ash content related to cement mass as well as the time of exposition has been discussed.
