What can be done to repair cracks in a concrete slab?
Answers:
you can repair these cracks with either mixing mortar mix and troweling in the cracks or purchasing a special concrete caulk.both are available at your local home centers, the caulk is very easy to use, just clean all loose debris out of cracks, apply caulk with caulking gun to cracks, use a rectangular trowel to work the material into the crack deeper and scrape the surface of excess material. let it dry and you are done. this is only an surface repair not a structural one-
good luck

I tried that tube of epoxy for concrete repair. Worked lousy. I repaired my porch by keeping area moist with water and applying Quick-Rite.
Aside from re-pouring the concrete with steel this time, anything will be a temporary fix.
