Alkalinity- protects or promotes embedded steel corrosion? 6

[Kenton54]

Do the alkaline properties of concrete help protect or promote corrosion of steel embedded in concrete? I've read it both ways. Who's right? -Kent

Simplicity, laxative, Johnie Walker. Yes, all the ingedients are there. Thank you.

Recipe....

Ingredients:
1 oz reagent grade phenolphthalien
10 oz isopropyl alcohol (70%)
6 oz Johnny Walker Black (JWB)

Procedure:

Inject 1 oz JWB onto tongue. Swallow quickly

Mix 1 oz phenolphthalien into 10 oz alcohol

Inject another 1 oz JWB onto tongue. Swallow quickly

Observe swirling in phenolphthalien/alcohol mixture. Watch for 30 seconds

Inject another 1 oz JWB onto tongue. Swallow quickly.

Observe concrete specimen, then mixture, then concrete specimen. Repeat

Inject another 1 oz JWB onto tongue. Swallow quickly.

Observe swirling in mixture again. This time for 60 seconds.

Inject another 1 oz JWB onto tongue. Swallow quickly.

Now try to find that concrete specimen again. Having difficulty? Inject the last oz of JWB onto tongue. I don't see any carbonation, do you?

I'm liking concrete inspection more all the time...
