What causes concrete scaling? - Effects and Fixing of ...

The general causes of the concrete scaling are as follows. Use of low strength or improper mix designed concrete with high water-cement ratio concrete which allows the water and the declining solutions to penetrate deeper. Use of non-air entering agents which results in poor air void system which causes the scaling at the surface
