What causes this? Standing water? What is the flaking? Bad cement mixture? or did the previous owner lay a veneer of cement over a previous walkway?

Totally. So when I resurface instead of including their Anti-Skid Additive, I think I'll just sprinkle a little sand over the drying coat.2. Using salt on the walk during winter.
I had filled the cracks with Vinyl Concrete Filler (in the tubes) and then coated the walk with a thin coat of Patcher mix. After the January cold snap, I noticed the darned cracks have reappeared. Evidently the cracks expanded and contracted, but the concrete patch over the top had nowhere to go.note there's no expansion jnt mtl showing so whatever repairs're finally done should consider the eventual movement & re-spalling.

Come spring, I'll need to repair this again before it starts flaking. I'm NOT gonna install an expansion joint. I guess I'll fill the cracks with vinyl filler and hope that no spalling occurs. I'll just need to be satisfied with that.
