I know Dad knew about wet cement curing. He had a job back when I was a kid helping to replace a millionaire's fairly long dock. The iron pipes supporting the dock were cemented in place to ground rocks on the lake bottom possibly 50 years earlier and under water ever since. Damn that was hard cement. We had to break it up and remove it. I remember asking him why the cement was so hard, he told me something about being under water for long periods made stronger chemical bonds. Still, I don't recall him misting the pillar caps he formed nor covering them with tarp to keep them wet. Thanks for those great tips!
