Hello Mr. Monther Alfitouri,

Honeycomb is not permissible even in any percentages in concrete where the reinforcement is exposed. 

A study states that - 5% of honeycomb can reduce 30% of the concrete strength.

However, honeycombing is not a severe issue for a small surface area subjected to the reinforcement not exposed.
