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?
