CAUSES OF HONEYCOMBING IN CONCRETE.
1. Over Reinforcement.
2. Stiff concrete use or the concrete is already set before placing it.
3. Improper vibration of concrete in formwork.
4. Inappropriate workability of concrete.
5. Use of larger size aggregates in excessive amounts.
6. Formwork is not rigid and watertight.
7. Concrete is poured from more than the allowable height.
8. The amount of steel in concrete also affects honeycombing. Heavy reinforcing in concrete does not allow concrete to flow easily.
9. Poor Workmanship.
Therefore; Concrete has a would of its own, it does not want to be told what to do. You ask Concrete for its cooperation in creating your vision. Then you listen, and if you listen effectively and close enough, Concrete would tell you how it would allow you to mould and shape it until it flows gently into the mould that it has created with you.
