Honey combing in concrete refers to the presence of voids or air pockets in the concrete mass, particularly around the reinforcement bars or in corners.

It occurs due to improper mixing, inadequate compaction, or poor workability of concrete. When cement concrete is not mixed properly, the coarse aggregates do not bind well with the mortar, leading to gaps and cavities.

This results in a weak structure, poor durability, and may expose reinforcement to environmental effects like corrosion.

While segregation and bleeding are also issues related to poor concrete practices, they are more associated with excessive water content or improper handling rather than just bad mixing.

Therefore, the most specific result of badly mixed cement concrete is honey combing.
