Different Types of Concrete Cracks.
1. Cracks due to Corrosion of Reinforcement: Corrosion causes expansion and cracking.
2. Structural Cracks: Caused by settlement or movement in the foundation.
3. Map Cracking: Network of fine cracks due to shrinkage or settlement.
4. Crazing: Fine network of cracks on the surface due to drying shrinkage.
5. Diagonal Cracks in Beams and Columns: Indicate structural issues like shear stress or torsion.
6. Expansion Cracks: Caused by expansion of materials like aggregate or reinforcement.
7. Plastic Shrinkage Cracks: Occur when concrete shrinks rapidly while still plastic.
8. Drying Shrinkage Cracks: Occur as concrete dries and shrinks.
9. Thermal Cracks: Caused by temperature changes.
10. Settlement Cracks: Occur when the foundation settles or moves.
