Annotation

The article presents an assessment of the effect of salt corrosion of concrete and reinforcement on the bearing capacity of the superstructure elements. It is shown that the load-bearing capacity of superstructures subject to salt corrosion is almost 2 times less than the load-bearing capacity of superstructures without salt exposure.

Keywords

salt corrosion
span
bearing capacity
salt corrosion effect
reinforcement.
