What Is Honeycombing In Concrete When the finished concrete surface shows the air void in it or the majority of aggregate with no mortar between them indicates the Honeycombing of Concrete. Honeycomb in concrete is caused by the mortar not filling the spaces between the coarse aggregate particles. Causes of Honeycomb These hollow pockets known as honeycomb occur when the cavities and areas of the space are not all filled or reached by the poured concrete. Three common causes of honeycomb in concrete include Stiff concrete is used. Stiff concrete is used. Improper vibration is used during the concrete process. There is less cover for reinforcement bars. Low concrete workability, i.e., improper w/c ratio Over-vibration of concrete Inadequate concrete compaction Addition of extra water to concrete mixture to increase workability Pouring concrete from excessive heights Formwork lacks proper rigidity and water tightness; hence grouts leak out of poured concrete High aggregate content and ov...
