Abstract

A method and an apparatus for measuring and monitoring salt accumulation on and in concrete structures that are exposed to splashes of salt. A measuring apparatus (100) is arranged in connection with the concrete structure (9) in such a manner that it is exposed to splashes of salt from, for instance, traffic. The measuring apparatus comprises a concrete measuring-body (1), a weighing device (3), a disengaging means (2), heating device (5) and a casing (6). The measuring body (1) is dried to a predetermined moisture content using the heating device (5) and is weighed. In an evaluation unit (200), the measured weight is compared with a known standard weight at the same moisture content without salt exposure and the salt accumulation on and in the concrete structure is calculated based on the weight deviation between the measured weight and the known weight.
