Title: Concrete chemistry
Post by: mike on February 23, 2006, 12:43:46 AM

Can somebody out there please explain to me the chemistry involved in concrete. Until today I had always assumed that it just "dried" and hardened. However it has been brought to my attention that there may be some sort of hydration reaction occuring, possibly exothermic I suppose. I would really like to know the chemistry involved in this process.

I can't really add anything myself, but you might try and take a look at:

Wow, great this is just what I needed, thanks. Anyone else interested in this topic should check out this article (I am just in the middle of reading it). :) :)

It seem the water is consumed to build complex structures of mainly calcium silicate hydrate, and not just drying. Apparently, one has improved the strength of concrete by adding substances with a carbon backbone and sulfate groups attached.

That's about what I could get out of my old textbook on general chemistry. I'm sure that article is more enlightening. :)

Perfect!  Is there an online link to this?

 :o >:(my Athens password won't get me in. My cheap ass University probably hasn’t paid for access. I'll have to check the library and that means I’ll have to hold a real book instead of the computer mouse. What is the world coming to; next I’ll have to write down lectures instead of printing off PowerPoint documents, and learn to spell rather than using spell-check.

Have you thought of maybe checking google news. Who knows, maybe you'll find that article for free somehow.
