Сильное солевое повреждение бетона зимой

A documentary close-up photograph of severe salt damage on a weathered concrete parapet wall in winter. Shot from a low oblique angle, with the wall receding into the distance along the right frame. The top coping has a thin layer of snow and frost, while the ground beside the wall is dark, wet, and covered in slushy snow. The concrete face features widespread scaling and spalling on the upper half, with irregular peeling patches exposing coarse aggregate stones, black and tan pebbles, and crumbling pitted edges from gray cement paste loss. Vertical moisture streaks and dirty runoff stains descend to the base. Soft overcast daylight, cold gray and charcoal palette, muted winter white, shallow atmospheric haze in the far background. Civil engineering inspection photo style, field-camera look, highly detailed surface texture, no people, no text.
