Have you seen a nest-like structure or to be more precise a bee comb-like structure on some concrete walls? Well, you must have. That is what is honeycomb structure in concrete. But I will tell you exactly what is honeycombing in concrete.
In concrete, honeycombs are hollow areas and voids that were left wherever concrete could not fill them. The primary culprits of honeycombs in cement are improper vibration and concrete's workability. As soon as the shuttering is taken off, it is simple to see honeycombs that are on the sides. Only cutting-edge methods, such as ultrasonic testing, can find honeycombs hidden beneath a mass of concrete.

Three varieties of honeycombs exist:
Small honeycombs are up to 25 mm deep.
Medium honeycombs are deeper but do not disclose the reinforcement.
Large honeycombs with a depth greater than 25 mm and exposed reinforcement.
Causes of the honeycomb structure in concrete
Concrete does not reach all areas, causing voids and hollow pockets to form, which causes honeycomb. The primary causes are
Concrete vibration that isn't appropriate.
Less protection for the reinforcing bars
concrete used is extremely rigid
The typical locations where honeycombs are seen are at the intersections of beams, columns, and one or more beams. This is because the beam and column rod reinforcement in one location is jumbled; when vibrating and pouring concrete, additional care must be used at this location.
Additionally, concrete cannot fill in the small crevices between both the reinforcement rods due to the higher percentage of larger aggregate present in concrete.
Effects of the honeycomb structure in concrete
Reduction in the structure's strength and bearing capacity.
Reduction in the structure's lifespan or durability.
Corrosion and rust on rebar.
Poor aesthetics
Enables air and water to enter the concrete.
Now you know
