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?

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.
