Ok, maybe one more thing... Tobin, I know concrete can dry under water, but not any concrete. In fact we know that the Romans developed concrete that dries under water.
Concerete does cure, but it starts with water in it. Are you saying that all of the hydrogen and oxygen molecules are converted in the (chemical) curing process, and none can be left as H2O?
I used the term drying as a general term that everyone would understand, and perhaps I should have said set. It’s as much the tone of the response as anything that caused me not to let go.
