Physical salt attack (PSA) is a key deterioration mechanism affecting porous materials like concrete when exposed to salt-laden environments. Damage occurs as salt crystals grow within the near-surface pores, generating tensile stresses on the pore walls that exceed the concrete's tensile capacity. This can lead to surface scaling, resembling the damage caused by freezing and thawing cycles. This presentation compiles current knowledge on PSA, including damage mechanisms, test procedures, damage assessment methods, influential factors, protective measures, and relevant code and guideline provisions. Additionally, it identifies areas requiring further research and proposes a classification system for concrete's resistance to PSA and a mitigation strategy.

1. Identify the distinctive visual signs of PSA on concrete surfaces.
2. Develop knowledge of the accelerated tests currently used to assess the potential of PSA on concrete.
3. Explain how key concrete mix design parameters influence the severity of PSA.
4. Recognize current strategies for mitigating PSA on concrete structures.
