Spalling e Corrosione del Calcestruzzo Costiero

A documentary inspection photograph of [severe chloride-induced corrosion damage] on a [reinforced concrete coastal structure], viewed from slightly below at [the corner of a cantilevered beam or pier]. A large spalled area at the outer corner exposes [5 rusted horizontal reinforcing steel bars] embedded in the concrete. Surrounding concrete is rough, cracked, and chipped with visible coarse aggregate and irregular broken edges. Brown-orange rust stains streak downward from the exposed reinforcement across the underside of the beam. The weathered concrete surface is light gray and matte with subtle pores and casting imperfections. In the softly blurred background, a calm blue sea and pale blue sky meet a faint distant shoreline under bright natural daylight. Authentic engineering inspection photo composition, with no people, tools, safety tape, text, or graphic overlays.
