Signs of Bad Concrete Pour

• Signs of Bad Concrete Pour during concreting
• Signs of Bad Concrete Pour after Hardening of concrete

Signs of Bad Concrete Pour During Concreting

• Bleeding.
• Segregation.
• Spalling of Concrete.
• Cracking of concrete.
• Scaling of Concrete.
• Honeycombing of concrete.
• Alkali Aggregate Reactions in Concrete.
• Crazing.
• Delamination of Concrete.
• Dusting.

1. Signs of Bad Concrete: Bleeding

Methods to Reduce Bleeding in Concrete

• Add a very less amount of water content in the mix of the concrete or use chemical admixtures to show that demand for water gets reduced and required workability is also achieved.
• Design the concrete mix properly add more amount of cement in the concrete mix.
• Proper measure and method of mixing should be used to reduce bleeding in the concrete.

2. Signs of Bad Concrete: Segregation

3. Signs of Bad Concrete: Spalling of Concrete

• Light: When the detected area of the concrete measures less than 150 mm in any direction or less than 25 mm in depth. This will be considered as a light spalling of concrete.
• Medium: When the defected area concrete measures between 150mm to 300mm in any direction or between 25mm and 50mm in depth. This will be considered as a medium spalling of concrete.
• Severe: When the defected area of concrete measures between 300mm to 600mm in any direction or between 50mm and 100mm in depth. It will be considered as severe spalling of concrete.
• Very severe: When the defected area of the concrete more than 600 mm in any direction or greater than 100 mm in depth. This will be considered as the very severe spalling of concrete.

4. Signs of Bad Concrete: Cracking of Concrete

5. Signs of Bad Concrete: Scaling of Concrete

• Light: The light scaling of the concrete occurs When there is a Loss of surface mortar up to 5mm depth without any exposure of coarse aggregates.
• Medium: The medium scaling of the concrete occurs When there is a Loss of surface mortar up to 6 to 10 mm depth with exposure of some coarse aggregates.
• Severe: The severe scaling of the concrete occurs when there is a loss of surface mortar up to 11 mm to 20 mm with aggregate particles standing out from the concrete.
• Very Severe: The very severe scaling of the concrete occurs when there is a loss of mortar and aggregate particles to a depth greater than 20 mm.

6. Signs of Bad Concrete: Honeycombing of Concrete

• Light: The honeycombing of the concrete up to a depth less than 25mm.
• Medium: Honeycombing of the concrete ranges to a depth between 25mm and 50mm.
• Severe: Honeycombing of a concrete range to a depth between 50 mm and 100 mm.
• Very Severe: Honeycombing of the concrete to a depth greater than 100 mm.

7. Signs of Bad Concrete: Alkali Aggregate Reactions in Concrete

8. Signs of Bad Concrete: Crazing

9. Signs of Bad Concrete: Delamination of Concrete

10. Signs of Bad Concrete: Dusting
