What is honeycombing in concrete?

Honeycombing is the term used to describe areas of the surface that are coarse and stony. It may be caused by insufficient fine material in the mix, perhaps due to incorrect aggregate grading or poor mixing.

What causes concrete honeycombing?

WHAT CAUSES HONEYCOMBING? Honeycombing is caused either by the compaction not having been adequate to cause the mortar to fill the voids between the coarse aggregate, or by holes and gaps in the formwork allowing some of the mortar to drain out of the concrete.

However, if honeycombing is left untreated in areas of possible moisture penetration, serious structural conditions such as concrete cancer could occur.

How do you treat honeycombing?

How can honeycombing be avoided?

Avoid honeycombing by using appropriate concrete mixtures with sufficient workability, proper placement and consolidation techniques. Honeycomb, subsidence cracks, cold joints and excessive surface air voids are common surface blemishes associated with ineffective concrete consolidation.

Is honeycomb concrete bad?

In general, concrete honeycombing is considered a cosmetic condition that can only be found on the exterior areas of the concrete pour. However, if left untreated over a long period of time, moisture could penetrate the exposed areas. This could cause serious structural conditions, including concrete cancer.

How do you know if a honeycomb is in concrete?

Honeycombs which are on sides are visible to naked eyes and can be detected easily as soon shuttering is removed. Honeycombs which are inside mass of concrete can only be detected by advanced techniques like ultrasonic testing etc.

What is honeycombing and how do you rectify it on site?

Honeycombing is a structural defect of a RCC Structure, areas of the concrete surface where the coarse aggregate are prominently visible are called honeycombed surface, giving a look of honey bees nest.

How can you tell if concrete is failing?

What happens if concrete slump is too high?

Increased porosity also results in more efflorescence, causing the color of the surface to be less intense or whitish. Excessive slump also can result from accidentally adding too much water-reducing admixtures or super-plasticizers to a mix. This can result in aggregate segregation and a serious loss of strength.

How do you stop concrete from deteriorating?

Deterioration of concrete can also be prevented by treating the concrete with solutions of suitable salts or even acids in minor concentration. 10. The durability of concrete can also be increased by impregnating the pores with a suitable polymer.

How do you smoke bees out of walls?
