Crete - Not everyone. Just those of us who have taken over contracts where Parking Blocks in asphalt lots have nearly completely deteriorated from years of heavy salting. YET the asphalt remains virtually unscathed.cretebaby;910891 said:
Where sidewalks have large pitting areas ONLY at the bottom of formed handicapped ramps (ie where salt may get slung) yet the remainder of said walks, even aggregate is unharmed using blends or calcium.
Want pics? I got plenty of examples I could share....

And isn't it the Mortons Saf-T-Salt bags that say "remove excess from concrete immediately to prevent damage" (or something to that effect - I could go grab a bag and give verbatim if its that important)

Yes please so we can explain the exact science AGAIN of it even though I already gave the "for dummies version" a couple posts up and there are sooo many threads already out there on this topic.beverlylawncare;911191 said:
Here is a repeat...
"Salt/ice melt increases the freeze thaw cycle which is the only reason why people see an effect from using these products. It just hastens the inevitable."
The reason why other products seem to not do as much damage is they have a lower freeze point which means there are less freeze thaw cycles that the concrete goes through..

Just finished reading a research paper from the Portland Cement Association..cement.org....They say that Magnesium and Calcium Chloride are MORE aggressive towards paved surfaces than Sodium Chloride which is almost benign...Take it for what its worth..Just my 6 cents worth...:salute:show-n-go;911142 said:

IMHPO, I would NOT use salt on these walks for a number of reasons:kbros;909958 said:
#1 The customer has requested NO salt. The contractor could have very well had a disclaimer in his contract against the use of de-icer's. Who do you think will be the first person everyone is pointing their fingers at IF the concrete would see winter damage?
#2 Most ready-mix associations DO NOT back the use of any deicers for the first winter, simply because the concrete may not have reached it's full strength potential yet. It is kind of a blanket I admit, but I would err on the side of caution.
#3 Whatever profit that could possibly be made selling de-icers could quickly & easily be burned up 10 fold in litigation. I learned long ago, "choose your battles wisely."
I couldn't find any info specific to Iowa, but here's a very simple opinion from my state's assoc.:

I think it boils down to..Whatever De-icer you intend to use..Use it wisely....More is not better..Use correct amounts for the situations...

I have a very large landscaping company, (that is owned by an even larger construction company), that has been buying Ice Ban from me for a few years that, they use exclusively on new concrete. Please take this for what it is worth, but they seem to be very happy with the results. I concur with the statement that salt does not chemically attack concrete. As said earlier, salt simply speeds up the inevitable. Bad concrete is bad concrete.
Exactly correct--bad concrete is bad concrete.Unfortunately,just about all masons add water to get more cream faster and to make the slump easier to handle.Usually, this seems to happen on residential or better explained--where there is no inspector watching for someone to give the quick signal to the concrete truck driver to add some water.My Dad was the easiest going guy around and knew every possible detail about all the intricacies of concrete,but even in 95* heat and for an electrical duct bank protector,if one of his men gave that cutesie signal to add water,he'd rip him a new one.More water ruins concrete,plain and simple.This is why everyone thinks salt damages concrete,because it does,but only on poorly mixed/handled concrete.kpmsnow;912401 said:

Combotherm it is a dow product.
Quick question you said paved....That to me is hot mix asphalt....Also I pave roads & driveways in the summer & you no those little small 1"-1.5"pot holes you know whats thats from, the guys dumping to much diesel on there shovels/rakes, the diesel eats up the "TACK" or emulsion what eva other parts of the country calls it.....it's not from MAG or CAL or SALTMatson Snow;911238 said:

If the Portland Cement Assoc. is talking about pavemant it's pretty safe to assume they are talking about porland cement concrete pavement.
The milk house floor in our dairy barn is all eaten up and has never seen a bit of salt.TommyMac;915519 said:
