1. Wastage of material is less as only the required length is cast
2. No case of stresses due to handling and driving and hence no extra reinforcement for these
3. Transportation is avoided
4. Time for curing is saved
5. No fear of breaking of piles and those are not blown by hammers
6. They can be designed for heavy loads by providing bulbs or pedestals
They have a higher handling cost
wood: wood can crack unlike concrete and wood is affected by water which can cause it to rot whereas concrete is not Metals: Metals can rust whereas concrete does not and metals can easily scratch Bricks: Bricks are more expensive than concrete and bricks take generally more 'man power' to place down whereas concrete does not. Hope this has been a good help
seggregation may take place.
300-500 US$ depending on area.
They are too numerous to mention! Steel embedded in concrete is protected from corrosion by the high alkali content of concrete. New concrete is 13-13.2 pH when poured. The chemical reaction that takes place between the concrete and steel forms what is called a 'Passivating Layer' on the steel. This layer, kept intact will prevent rust from occurring on the steel. Google, passivating layer and read. It is very important to keep this high pH during a concrete structures life. One way this is done is to waterproof the concrete. Aluminum doesn't share this characteristic and corrodes quite easily when placed in concrete. This why, if an Aluminum railing post is to be embedded in a concrete a core is extracted, an appropriate filler material is placed in the hole, then the Aluminum is inserted. Filler materials [usually an epoxy] isolate the Aluminum from contact with the concrete and also prevent electrical currents from flowing. If aluminum is IN the concrete, Dissimilar metal corrosion begins day one between steel and aluminum. In short order the aluminum will be a powder. Steel cost less, easier to work with and can be welded conventionally on site.
Pre-stressed concrete is made by using,high strength steel bars(tendons).normal concrete(>M25)sheaths for cable duct.anchors.jacks.
Advantages of concrete:compression member.slabs.beams.shear walls.Disadvantages:Non-renewable source.Mix design should be known.Skilled labour is required to mix, handle, and place the concrete.
the advantages was that they ave the right to access trade from place to place.

the burj al arab foundation process is done in 4 stages. in the first stage temprary piles are drove.in 2ed stage rock island formed with the help of these droved piles hydraulic fill layers bund to dis place water from island. in 3rd stage permanent concrete armour is made and then in sea sand concrete friction piles r used.... there r 230 friction piles r used to cover the area of whole island
