1st thing, that study did not show anything on the quantities they used. At the correct application rates, we have never found any damage to concrete we have treated. I have jobs that we have used CC on the walks for almost 20 years at much higher rates than used in lots with no damage. They can do all the studies they want, I have decades of hands on experience with it and I disagree.

Second. I have poured literally thousands of yards of concrete. During the colder months, CC is added to the concrete as it reacts with the water and creates heat which helps the concrete set before it freezes.

So have I, but it doesn't mean that it's recommended. If you ordered CC in concrete that required steel re-inforcement on a decent sized commercial job that required some kind of oversight/testing, you wouldn't be getting paid for your work. This isn't the 1950's anymore, and there's far better and safer alternatives to CC nowadays............

According to the American Concrete Institute, the
rate of chemical attack of calcium chloride on
concrete is “negligible”.
1
In an article titled, “Winter Weather, Deicers Need
Not Damage Concrete,” published by the Portland
Cement Association, calcium chloride is called one of
the “safest deicers for concrete”.
2
Independent laboratory tests produced results
consistent with the above statements.

The data indicates that scaling from calcium chloride was less
than that of other deicers, and comparable
to that of pure water.
