Honeycombing in concrete can be formed due to the improper consolidation of concrete. If Concrete is not consolidate when it is placed inside of form work air voids could remain between the forms and the concrete creating honeycombing. Proper consolidation can be achieved by the use of vibrators.
By means of proper compactionBy adopting appropriate water-cement ratiosegregation and bleeding should be prevented
Concrete is economical, easily formed, durable, has good strength under compression loading and can be finished in many aesthetically pleasing textures.
None. Concrete may be formed without metal.If you are reinforcing the concrete with rebar then it depends on what loads the reinforced concrete will have to bear, the dimension of the rebar, the safety factor involved, and lots of other geometric factors.Steel bars quantity will be according to structure element; but a (very) rough average of 120 KG per cubic meter.
Prefabricated is a general term for anything that is assembled in a factory rather than on-site. Precast would be specifically applicable to anything that could be formed in a mold (concrete, perhaps glass, metal, etc.).
Cast in place. Concrete is poured where at its permanent location. For example, a manhole cast in-situ will be formed and poured at the pipe connection. This is the opposite of pre-cast, meaning it is cast off-site and transported to its permanent location.

Honeycombing - is pockets of air trapped during the mixing process. The air-pockets stay in the mixture while it hardens - leaving a weaker area where the honeycombing has occured.
concrete is formed from limestone by the combustion of the limestone (heating of the limestone)!
Vibration is a process by which fully compacted concrete is achived.Importance:Prevents honeycombingPrevents segregation and bleeding of concreteExpuls air from concrete.
It is a manmade concrete structure.
unlike standard concrete which is in a liquid form and poured were it is needed and formed, precast concrete is molded offsite into the form that is required and then shipped to the site where it will be set into place.
A concretion is a rock formed from sedimentary processes; therefore, it is a sedimentary rock.
Concrete is economical, easily formed, durable, has good strength under compression loading and can be finished in many aesthetically pleasing textures.
section of solid concrete that results from stopping the deck on each side of the girder in a composite floor system constructed using a formed steel deck.
Masonry implies bricks, blocks, or stones held together with mortar. Bricks are fired ceramic. Blocks are usually formed concrete. And stones are formed naturally and quarried from the earth. They are held together with mortar. Concrete is used as mortar, but concrete can also be poured to make slabs and foundations. I think the difference is that concrete can be used by itself without being considered masonry. For example, even statues can be made from concrete by pouring them into a mold.
There is no abstract noun form of the concrete noun 'shell' or the verb to 'shell'.
