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. This can be corrected by increasing the sand and cement content of the mix and by proper mixing, placing and compaction. Alternatively, honeycombing may be caused by leakage of grout or mortar fraction from the concrete at construction or formwork joints.

Hai, everyone. Please pay attention.

Segregation main cause when less binding material use and poorly graded coarse aggregates are use and water use in more quantity results separation of coarse particles.

Bleeding due to excess water and due to improper mixing. Concrete leads to honeycomb as. Pores are left. In concrete improper vibration. All leads to honeycombing.

Don't confuse. Thankyou.

Honey combing is the correct answer.

This is caused when the gravel, cement and water are not properly mixed together. When the water content is too little, and the concrete is poured into the structure, the mixture will not settle properly causing the water to drain from the top and settle on the bottom. This would result in the small holes appearing on the surface.

According to me options a b& c, all these happen.

- segregation means separation of coarse &fine aggregate.
- bleeding means separation of excess water from concrete.
- honeycombing means the formation of voids appears in form of a honeycomb.

All these phenomena happen because of bad mixing.

Segregation is due badly mixing of concrete. Bleeding is over compaction of concrete via vibrator etc and honey combing is a result of Lean mixing of concrete of improper compaction while pouring the to congestion inside the concrete body.

Segregation is the right answer.

Segregation causes due to non-uniform mixing.

Bleeding is due to excess water.

If it is not vibrated properly.

So badly mixed is nothing but nonuniform mixing, Therefore Segregation is directly attributed to a bad mix.

Therefore, the answer is Segregation.

I think option D is right because honeycombing Is occurs due to less compaction, bleeding occurs due to excess of water and segregation is occurs due to all mixture should not mix properly but this question is wrong because of badly mixed means many types.

Honey combing is caused by insufficient fine material in the mix, perhaps due to incorrect aggregate grading or poor mixing. This can be corrected by increasing the sand and cement content of the mix and by proper mixing, placing and compaction.

Honey combing is the right answer because segregation is due to improper placing and bleeding is due ti an excess amount of water when we have to mix in the concrete mixture. So honeycombing is the right answer here.

Badly mixed concrete means not uniformly mixed so result in honey combing. Segregation is due to the separation of ingredients rather it is well mixed. Segregation may be in the time of transportation and pouring.
