Can chipped concrete be repaired?

How do you fix brittle concrete?
Mix two parts sand to one part cement to get a super-strong mixture. The secret trick to get this material to permanently bond to your existing concrete is to apply a coat of cement paint to the rough concrete just a moment before you apply the patching mixture.
Why is my concrete chipping?
When the temperature drops below freezing, moisture in the concrete tends to expand, creating internal pressure. Over the course of a winter, or over the course of years, as the internal pressure rises and falls, it stresses the surface layer of the concrete, which leads to spalling.
How do you chip concrete?
Use electric jackhammers and electric rotary hammers to chip it away. Jackhammers are powerful pounding tools with various chisel-like tips to break up concrete. To pound 2- to 4-inch walls, you can use a demolition hammer.

How do you fill large gaps in concrete?
Wide cracks in concrete are best patched and sealed with a concrete patching compound. Smaller cracks, less than 1/4 inch wide, can be repaired with a concrete caulk or liquid filler. Patching compounds typically are mixed with water and applied with a trowel.
What does spalling concrete look like?
Spalling concrete can look like round or oval depressions along surfaces or joints. Spalling tends to be most common in cold climates when de-icing chemicals are applied or when seasonal freeze-thaw cycles damage the concrete.
Is there anyway to fix a bad concrete job?
In most cases, a poor concrete job cannot be saved; the slab should be removed and a new one poured in its place. If the visible finishing was done poorly then you can assume there are other hidden problems that will soon appear.
