Something is amiss. Even Newt wouldn't use that many elipses…or dots…or whatever the hell it is that

the longest lasting concrete takes compression loads, not tension loads. it also contains no steel.*
*super controversial today, but it's why we see so many older cement structures still in good shape

No one seems to have mentioned curing properly for concrete longevity. We did a lot of concrete pours in my day as a factory journeyman carpenter. The most interesting pours were when we had to sandbag the perimeter of the job and flood with water. This slowed down the curing and made for some super durable concrete.

yes! I remember old guys wetting down the freshly poured cement with a garden hose in the 70s as a kid, even.

Just never put chemicals on it...even if they claim they are safe for concrete.
Learned the hard way by having to pay for replacement of front sidewalk...twice,
Now I just spread oversized painter's tarps when the forecast calls for ice.

That would definitely get the neighbors talking around here.

We had some work done about 15 years ago, and the mix was a little dry on one of the several pours. We've fought spalling just on those pads ever since. (TBH, the one closest to the street gets extra abuse from the road salt.) The other pads are near perfect.
We almost never use salt. I'll throw down some salt on the steps when I'm expecting company and just can't get it deiced in a timely fashion. That's maybe once or twice a season, sometimes never. Most of the time a thorough removal and a little sunshine does job.
