discusses rebar corrosion (I suspect this is corrosion of spots close to surface, not actually a critical problem)
Anyone noticed further wear on busway surface over the summer? - subjectively I would say that aggregate is sticking out proud of the cement surface level to a greater extent. I'm wondering whether the air-entrainment of the concrete (inclusion of small air bubbles) to guard against freeze-thaw damage is making the surface wear faster.
