Honeycomb in concrete

🔸🔸 @IESCIVIL 🔸🔸

What is Honeycomb?

---**Honeycombs** are hollow spaces and cavities left in concrete mass on the surface or inside the mass where concrete could not reach. These look like honey bees nest.


🔸🔸 @IESCIVIL 🔸🔸

Causes of honeycomb in Concrete:

1 .Insufficient compaction to concrete.
2 .Less cover to reinforcement bars.
3 .Improper Workability in concrete
4 .Concrete already set before placing .
5 .High concrete free fall while pouring
6 .Form work not watertight/rigid.
7 .More coarse aggrgegates than designed mix proportions and over sized aggregates.
8 .Improper placement of bars at column and beam junction.
9 .Addition of more water than designed at site for achieving workability.
10 .Steel congestion not allowing concrete flow to all corner.
