Chlorinated Water and its Effects on Concrete Reinforcement
Chlorinated Water and its Effects on Concrete Reinforcement
(OP)
All-
I am designing a reinforced concrete retaining wall for a community pool. I am trying to understand the effects of chlorinated water on concrete and concrete reinforcement.
A few questions:
Is chlorine infiltration synonymous with chloride infiltration?
Does chlorinated water have a serious corrosive effect on uncoated reinforcement? Is it on par with exposure to deicing salts?
Is there a standard for swimming pool design?
I am sure this topic must have been covered before, so any links to past discussions would be helpful.
Thanks,
MJB

RE: Chlorinated Water and its Effects on Concrete Reinforcement
While on the topic of pools-- any suggestions on / war stories about joint sealant products would be welcomed.
I am looking at WR Grace's "DECK-O-SEAL" product for my floor / wall joints since it is resistant to chlorined water. Any comments?

If you use a good mix with a low water cement ratio (<.45) and adequate cover, the chlorinated water shouldn't ever get to your bars, much less corrode them. Plus all pools have plaster or pebble tek coatings that are water resistant. I would not advise coating the reinforcing. it's way more trouble than it's worth.
When we design a chlorine contact basin we use our regular design procedures. As a matter of fact, we have places that are much more aggressive than chlorine environments.
De-icing salts are much more aggressive.
