Polished Steel Compaction Factor Apparatus, For Industrial, Industrial, Certification : CE Certified

Compaction Factor Apparatus
As per IS1199:1999 Compaction factor test apparatus consists of,
 1) Two conical hoppers and a bottom cylinder which is arranged as shown in below fig.
2) Steel rod of 1.6 cm Diameter with a length of 61cm is used to tamp the concrete
3) Weight balance is used to weight the concrete.
Compaction Factor Test
 
Compaction Factor Test Procedure
The sample of concrete to be tested shall be placed gently in the upper hopper, using the hand scoop. 
The hopper shall be filled level with its brim and the trap-door shall be opened so that the concrete falls into the lower hopper.
Certain mixes have a tendency to stick in one or both of the hoppers. If this occurs, the concrete may be helped by pushing the rod gently into the concrete from the top.
Immediately after the concrete has come to rest, the cylinder shall be uncovered, the trap-door of the lower hopper opened, and the concrete allowed falling into the cylinder. 
The excess of concrete remaining above the level of the top of the cylinder shall then be cut off by holding a trowel.
Weight the cylinder with concrete to the nearest 10 g. This weight is known as the weight of partially compacted concrete (W1).
Empty the cylinder and then refill it with the same concrete mix in layers approximately 5 cm deep, each layer being heavily rammed to obtain full compaction.
Level the top surface.
Weigh the cylinder with fully compacted. This weight is known as the weight of fully compacted concrete (W2).
Find the weight of the empty cylinder (W).
