Local concrete guy told me today not to put any rock salt on any of the local concrete….
He said that he salted some of his own concrete before and it left “pot marks” and that he had to fix the concrete …..
I’m in the panhandle of texas. It doesn’t get too cold here for too long. His remarks threw me off a little, kinda got me to questioning everything. Rookie here; this will be my first season dealing with ice/ salt. Any ideas?!
aren't roads made from "local" concrete?

Salt shouldn't be used on any concrete. local or not.

Calcium Chloride, some guys use magnesium chloride. Calcium is about $22.00 per 50 lb bag vs. about $35.00 per 50 lb bag here. I have seen new (less than 1 year old) flake off the top of the concrete after only a few applications of salt.

You ever read the study that Michigan Tech did about sodium vs mag vs calcium chloride?

Do you know what causes spalling of concrete?

Does Pennsylvania not use salt on bridges or concrete roads until it is a year old?

If you want the summary...sodium chloride does not physically or chemically harm concrete. Mag chloride is the worst, followed by calcium chloride as depending on the makeup, can chemically harm concrete.

Then to throw some for a loop...calcium is used in concrete in cold temps to speed curing.

Anyways, if I've said it once, I've said it 100 times. Properly formulated and properly installed concrete will not be damaged by salt. This is an indisputable fact. The problem comes in with either crappy redi-mix companies and/or crappy contractors who either don't order the correct product or screw up the installation. Even then, sodium chloride does cause spalling, freeze/thaw cycles cause spalling.

100's if not 1000's of miles of curbs, roads and bridges are built every year using concrete. Municipalities do not wait a year before applying sodium chloride to these roads and bridges. We have applied sodium chloride to 1 month old concrete parking lots, sidewalks, curbs, without any damage.

So @LubbockRoots , you need to more research. Ask the contractor why it will damage it? What does he recommend? Talk to some redi-mix companies and ask what they recommend? If you were further north the answers would be simple.

Hopefully ewe didn’t wait a year to store salt on your new concrete, bin last year…

Looks like this ones under control, no need for my drunken antics…btw, lone star seement is pretty big, and I’m pretty sure they own/bought out at least 1 of the larger suppliers in this area years ago…I don’t use them though, they suck…I only use “local” seement, in which hungry salt doesn’t like. My salt bin seement floor has held up quite well btw

Redi mix guys are giving me a hard time. Over all I’m hearing just don’t do it followed by laughs…. I’m not buying concrete so they done care…
a buddy works for DOT and he said the stuff they use is called Melt Down 20. He also said it’s extremely corrosive.
I have a quote for Sodium Chloride at $4.00 a bag. Site One just quoted me 9k for a truckload of Excalibur ice melt…

Looks like Melt Down 20 is mag with some sand. They also claim it's low corrosive. What a crock.

Xcaliber is potassium chloride (basically worthless), sodium chloride and calcium chloride.
