This is when the top surface of the concrete is separated from any underlying concrete. Besides, hardening the concrete top layer before hardening the underlying concrete leads to delamination.
This is because air bleeding and water from underlying concrete will get struck between the two surfaces, forming space. Delamination can be avoided by utilizing appropriate finishing techniques.
Cracking is generally formed on the concrete surface due to different reasons. The top reasons include omission of contraction and expansion joints, improper mix design, unsuitable sub-grade, utilize of excess slump concrete mix, among others. To avoid cracking, you need to use low water and maximize coarse aggregate concrete mix. The surface should also be prevented by rapid evaporation of the moisture content.
This is the formation of loose and fine powdered concrete on hardened concrete via disintegration. Basically, this happens because of an excess amount of water presence in the concrete. And it causes to bleeding of the water from concrete. To prevent dusting, someone is advised to use the water-reducing admixtures to eventually obtain an adequate slump. Also, you can consider using better finishing methods and start finishing after removing bleed water right from the concrete surface.
