Plywood for concrete forms

[Rock knocker]

You were the first person to use the word "cement". The nitpickers on this thread may point that out to you in a negative way!!!

Nope, my usage was absolutely correct. Concrete is a product of various aggregates and hydrated lime cement. I was giving the formula from the hydration of cement.

Didn't say you weren't correct. Your statement implied that the hydration of cement was the same as the previous discussion of hydration of concrete.

That the product is CaO.2SiO2.4H2O, which is a hydrous material

Anything is hydrous material until dry or cure.

lol...

Add a little lime and Portland to mud, and your definition works. But is that really concrete?

The hydration of cement is the only hydration that takes place during the creation of concrete, so they are the same thing. The sand and rocks do not hydrate.

The formula shows that the water remains and is part of the molecule that is hydrated cement. Just like mica and amphibole are hydrated minerals.

I think you just made Snobdds point.

Man, this got stupid

No. He doesn't understand hydration at the molecular level

lol. Ok Mr. Expert.

And your chemistry CV is?
