Concrete spalling
Concrete spalling
(OP)
The sidewalks has been poured 3 to 4 years back. Recently the sidewalk concrete spalled at several locations. In our opinion the spalling is a problem related to finishing and workmanship. The contractor is blaming deicing chemicals for the problem. Could any one provide more information on other factors cause spalling? Few photographs showing current conditions are attached. The concrete was exposed to freeze and thaw cycles during winter months.
Thanks to all

There are several other causes for scaling: The mason(s) may have finished the concrete too soon - the bleed water was still on the surface; they may have overworked the finishing; or didn't cure it properly.
