I agree overall, but am curious: Having only briefly lived in colder climes, what about concrete doesn't hold up well in snow?

- sp332 10y agoFreezing water expands in little cracks and makes them bigger.
- MCompeau 10y agoWater leaks into cracks and cervices when its warm and then freezes when its cold. Since the ice expands and concrete has negligable tensile strength the cracks and crevices expand even further and the material begins to chip away and crumble.
- guyzero 10y agoWater penetrates the surface causing the surface of the concrete to flake off and eventually rusts the encased rebar which expands as it rusts which eventually cracks the concrete from within. The Gardiner Expressway in Toronto is a good example of this - it seems as it's permanently under refurbishment.
