How do concrete gaps keep the concrete from cracking during the winter?
During winter when the concrete contracts/shrinks and there is no gap, then it will crack from the surface. So gaps are left in concrete such that it can shrink to a safe limit without cracking it.

Why are there cracks on concrete paths?
Concrete has great compressional strength but very weak torque resistance. That means when the ground underneath concrete paths settles or erodes the concrete will crack. In order to determine where the concrete will crack the constructors leave faults in it. So when the concrete does crack it does so in such a manner that the path is still functional and aesthetic.

Why gaps are left in concrete slaps?
With the weather the concrete can expand or contract and the gaps in the concrete are left to allow for this expansion of contraction so the concrete doesn't crack or break.
Why are there gaps between the slabs of concrete pavements?
There are 2 reasons for that. Reason one: They can be expansion joints. In the winter the pavement contracts and in the summer it expands. these joints are generally gaps that go the whole way threw the pavement. Generally these joints are filled with some sort of caulking to keep moisture from getting underneath the pavement. Reason two: They can be put there as joints for the concrete to crack. when sidewalks are made and other concrete pavements, they anticipate the concrete cracking, so they put in gaps that dont go all the way threw the depth of the concrete as a place for the concrete to crack and not be unsightly.
Should concrete crack within days of being poured?
It could, but it should not crack. Either the grade was not prepared properly, the concrete was used too soon, the concrete was not reinforced, it was allowed to cure too quickly, or some other problem existed.
Can you pour concrete into a column and it not crack?
Yes but concrete is going to crack if it has too much stress. If it's a decorative column then use a 4000 mix. If it has a load on it you will have to figure how much weight is going to be on it.
