“Oxidation”

Steel expands 10x in volume when it rustscausing concrete to crack and fail.

How much energy does it take (on average) to produce 1 kilogram of thefollowing materials?

Steel (from recycled steel): 6-15MJ (1,665 to 4,170 watt-hours).

Iron (from iron ore): 20-25MJ (5,550 to 6,950 watt-hours)

Steel (from iron): 20-50MJ (5,550 to 13,900 watt-hours)

GBar (Pultrusion): 382 to 2,514 watt-hour
