Steel stanchions and Durisol blocks and insulation

[Ferdinand]

I think that is also the shortcuts of every Windows machine since at least 1990 to my knowledge.

 

Although I am impressed with youngsters who know about it; driving a laptop from a keyboard with alt and windows-key codes rather than flubbing about with mouse pads, and semi-colons, are established ways of intimidating non-nerds aged under about 35.

 

Though I am entirely baffled by people who type on mobile phones with their thumbs; Generation Millenial must have Trump-hands.

There's no issues in surrounding the steel column in that sketch with concrete. Concrete in that situation would protect the steel from corrosion. Locations where the steel is not surrounded by concrete (eg the face) should be painted to provide corrosion protection.

 

IIRC my O level chemistry, rust requires all 3 of water and air and iron, with water as the facilitator.
