Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). [1]
This means it packs together really well, and the absence of any wind on the surface — we've been over this, there's no atmosphere for wind — means those footprints won't degrade anytime soon ...
