I never expected I would be spending so much time mixing concrete on this residency … !
I learnt quite a lot about it! To mix the best quality concrete you need to use minimal water, make a workable but not sloppy mixture. When you shake it (and you must, to get the air bubbles out) it becomes less stiff and more fluid! It’s one of those weird, slightly fascinating, and yet at the same time very boring substances.
