SALT AND CORROSION - DO WE SEE THE RELATION MORE CLEARLY TODAY?

SALT OCH ROST - SER VI SAMBANDET KLARARE I DAG?

Since sanding of roads in order to prevent slippery conditions is satisfactory only for short periods, salt is spread to lower the freezing point. However, if the resulting slush is not removed quickly, it causes corrosion. Investigations began in the middle of the sixties, but the effect of salt is still not quite clear. Addition of inhibitors to salt has no effect. Generally, the moister, warmer and more polluted the atmosphere, the higher the rate of corrosion. Studies on the west coast showed that, obviously due to the natural salt content of the atmosphere, road salt had no appreciable effect on corrosion. Tests carried out on stationary plates and plates mounted underneath lorries showed that corrosion on mobile samples was double that on fixed ones. It would appear that once concentration of corrosive substances has reached a certain point, a rise in this concentration has no appreciable effect on corrosion. /TRRL/
