How to seal crack in concrete floor?
If the crack is large, you'll have to get some more concrete and use it to fill the crack. If the crack is small, you may be able to simply patch it. If you plan on coating the floor with some type of epoxy floor coating, you may be able to simply leave the cracks alone before application, simply allowing the epoxy material to fill the cracks. The work will still come out evenly and the epoxy will actually hide the spot where the crack was once located.

Can you put more concrete on top of old concrete?
Yes, if the base is stable the new layer will bond and create a new, fresh surface.An unstable base will give bad results. You should pressure wash the old concrete to get rid of loose and spalling concrete and you should use a bonding agent to serve as a primer to get the new layer to bond well to the old.Obviously, if the new concrete is laid over concrete that is subsiding because of a sinking foundation, the new concrete will crack. You need to stabilize the old concrete before pouring new over it.If you put new over old, it needs to be at least a couple inches thick else it will not cure properly. If you simply want to improve the surface, there are special self-levelling concrete mixes that can be poured thinner and still be strong. Take a look at the link below for a good how-to.

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.
