Different types of Cracks in Concrete.


1. Plastic Shrinkage Cracks Hairline cracks in fresh concrete surface due to rapid drying.

2. Settlement Cracks – Diagonal cracks caused by uneven foundation settlement.

3. Drying Shrinkage Cracks – Random, map-like cracks due to loss of moisture.

4. Thermal Cracks – Long, straight cracks from temperature changes.

5. Structural Cracks Wide and deep cracks indicating structural failure.

6. Crazing Cracks Fine, surface-level hairline cracks (looks like a network).

7. Corrosion Cracks Rust-colored cracks caused by expansion of corroded rebar (steel inside concrete).

8. Alkali-Silica Reaction (ASR) Cracks – Map-pattern cracks with white gel due to chemical reaction inside concrete.

9. Overloading Cracks – Vertical cracks formed due to excessive load or weight.
