Hey pal,
Concrete is porous in nature, The climate and the products stacked on top of the concrete slab impact the life of the concrete. I will tell you ‘why does concrete spall’. In colder climates then concrete undergoes an ice-thaw cycle where the top layer of the concrete can crack. Spalling affects framed buildings, multi-story car parks, bridges, jetties, tanks, and bunds.

Concrete spalls for various reasons, it leaves the surface looking uneven. The aggregate layer underneath the concrete gets visible.

- Fire :Exposure to fire causes the concrete to change to stem. It creates expansive pressure in the concrete layer.
- Corrosion :Reinforced steel gets corroded and occupies more volume than before. The new-sized pipes within the concrete wall create pressure. Scaling occurs because of pressure.
- Joints :When joints are displaced due to improperly constructed joint structures, the concrete tends to spall.
- Shrinkage :The space between the top coat and the bottom coat moves due to bond failure. The bonding grout dries up and the concrete layer spalls.
- Quality :Low-quality concrete has a tendency to stall. You should use high-quality materials in your real estate construction.
Few other spalling concrete causes :
Improper curing / poor finishing techniques
Bond failure in two-course construction
Electrochemical reactions (such as from de-icing salts)
Corrosion/oxidation of reinforcing rebar (due to water exposure)
Subpar quality concrete
The wear and tear of the freeze-thaw cycle
This is all from my end on why does concrete spall.
