Concrete culvert pipe "treatment"
Concrete culvert pipe "treatment"
(OP)
Hi folks:
I'm a real old guy. When I was a kid in western New York State, the county highway department was a big operation. They cast their own concrete pipes for culverts and maybe storm sewers. These were 2 to 5 feet diameter pipes.
Each one was dipped in a hot tar bath heated by steam.
Why, since back in 1930-40's I doubt that any salt was used on roads, only cinders. They had stockpiles of cinders like you would not believe. Hundreds of cubic yards.
I did see plenty of calcium-chloride empty bags in one of their sheds. Maybe as an additive to concrete then?
Any thoughts?

I'm not sure there is much contemporary use like the latter in large amounts, perhaps due to at least worries of corrosion of reinforcement, increasing drying shrinkage, or other deleterious effects.
It's good to hear from us older folks (keep em'coming!)

I have seen it used in tractor tires as well..

What a mess with 300 pounds of steel tire weights to remove, as well as protecting the well from seepage (corrosive for steel). There is a buried tank surrounding the well casing.
A farm repair guy fixed things and added more chloride fluid. It's corrosive stuff. Grass killed at one area still has not come back.
So far the well water tastes fine???
