Abstract—The possibility of reducing the time required for testing corrosion inhibitors for reinforced-concrete
specimens is considered. The constant supply of water to the specimens with the addition of no less than 3%
chloride ion to concrete and constant-anode polarization with a low-power source are shown to ensure the accel-
erated transition of the reinforcement elements from a passive state to active dissolution. Under the conditions
of such dissolution, the efficiency of IFKh-90 and MCI 2020 inhibiting additives to concrete is assessed.
