Urea, from garden centers or farm supply places.
Acts like salt but doesnt trash concrete the same way. PLus it acts to a slightly lower temperature than salt does. |

That's more like what I was looking for, the concrete steps leading up to our house and beginning to dissolve with the salt we used to use!! :blink:

Re: Salt Alternatives
Probably just not the best quality concrete. My limited understanding is that neither salt or urea chemically attacks the concrete, its the fact that it creates liquid water that can then freeze/thaw/repeat and that is what can cause concrete to break down due to the mechanical pressures exerted by the freeze thaw action.
Decent "air entrained" concrete is better able to withstand the cycle, straight concrete doesnt do very well. Urea is better for the concrete because it needs colder temperatures before it freezes, so you dont get as many cycles. And as its a fertiliser it wont kill off any colateral vegitation the same way salt can. |

Of course you just move to somewhere that isn't a frozen hell hole.

Gold Star - you are correct. Also, when finishing concrete, the top layer is mainly paste with little air voids.
Thank you both! :thumbsup: |
