What Is The Procedure Of Concrete Compaction In Piling

What is Compaction of Concrete? Detailed

The following points are considered while placing and compaction of concrete over roof slab and in beams. Always use chutes lesser than 4.5 m in length or angle of inclination at 45° to horizontal in order to pour concrete. Fill concrete to the required depth only and vibrate it until the entrapped air inside concrete is released.

COMPACTION OF CONCRETE – PURPOSE,

17-02-2016  Compaction is the process that expels entrapped air from freshly placed concrete and packs the aggregate particles together so as to increase the density of the concrete. The compacting and finishing of concrete are generally two separate operations but sometimes, particularly with flat horizontal surfaces, they become parts of the one operation.

What is Compaction of Concrete - GharPedia

Theoretically, compaction of concrete is the process adopted for expelling the entrapped air as far as possible from the fresh concrete to achieve the highest possible density of the compacted mass. It simply means that there shouldn’t be any void present in concrete.

Method Statement for Piling Works at

Piling Works from the existing Ground Level – Casting and Boring of Piles. Prior to piling works, the site platform should be prepare and maintained in a dry and safe condition. The platform level should be installed at the existing ground level. The Surveyor checks and verifies the platform level, cut-off level, concrete and steel cage levels.

Pile Foundation Construction Procedure

The tremie method of concrete placement is used for the concrete pouring of the pile foundation. This method uses a vertical pipe, through which concrete is placed by gravity feed blow water level. The lower end of the tremie pipe is kept immersed in fresh concrete so that concrete rising from the bottom displaces the under ground water.

How does piling work – foundations

Piling is a type of deep foundation, used to transfer the load to a deeper level than is possible with a traditional shallow foundation. Vertical columns of concrete, steel or wood, or a combination, are driven deep into the ground to give extra support to the building that sits on top.

Compaction factor formula of Concrete-

The strength of the concrete doesn’t only depend upon the grade of concrete i.e. actual mix ratio of the components but also the application of fresh concrete, its workability, procedures of preparation, and its compaction during its fresh form.

Compaction Factor Test of Concrete Procedure

Compaction factor test is more precise and sensitive than the slump test and it is particularly useful for concrete mixes of very low workability as are normally used when concrete is to be compacted by vibration. Such concrete may be consistently fail to slump. Compaction factor test was developed by Road Research Laboratory in United Kingdom.

Compaction Factor Test On Concrete Lab Test

Compaction factor test on concrete is a very sensitive test and can be used even for the concrete with very low workability which cannot be done by the slump test. This test is known as the compaction factor test because the degree of workability is defined as the amount of work required for placing and compacting fully.

Why are vibrators not used in concrete

Since concrete is designed to be self-compacting,vibrators are not used for providing further compaction. Moreover, the concrete in piles is compacted by energy derived from free falling. However, if vibrators are used, the vibrated concrete may be compacted to the sides

Method Statement For Vibro Compaction Works –

Vibro compaction technique is applicable and effective for the improvement of loose natural fine sands as well as the compaction of Fills. Relative density is improved, potential for liquefaction from a seismic event is reduced, improvement depth up to 20.0 m or even much deeper can be achieved with this technique depending on the size of equipment used.

Standard Proctor Compaction Test - Civil

Proctor (1933) developed a laboratory compaction test procedure to determine the maximum dry unit weight of compaction of soils, which can be used for specification of field compaction. This test is referred to as the Standard Proctor Compaction Test. It is based on compaction of soil fraction passing No. 4 U.S. sieve.
