OVERVIEW

Used for determination of compaction factor of fresh concrete with nominal maximum size of aggregate not exceeding 40 mm as a measure of its workability. It is particularly suitable for mix of stiffer consistency.

It comprises the following :

  • Two conical hoppers with trap doors.
  • One cylindrical receiver 0.005 cu. m. volume.
  • A welded steel stand for mounting the hoppers and the receiver co-axially at specified distances.
  • Two trowels.
  • One hand scoop.
  • One standard tamping rod 16 mm dia x 600 mm long.



SPECIFICATIONS

Technical Specification

  • The Compaction Factor Apparatus, consisting of a rigid frame that supports two conical hoppers vertically aligned above each other and mounted above a cylinder.
  • The top hopper is slightly larger than the bottom hopper, while the cylinder is smaller in volume than both hoppers.
  • To perform the test, the top hopper is filled with concrete but not compacted.
  • The door on the bottom of the top hopper is opened and the concrete is allowed to drop into the lower hopper.
  • Once all of the concrete has fallen from the top hopper, the door on the lower hopper is opened to allow the concrete to fall to the bottom cylinder.
  • The excess concrete is carefully struck off the top of the cylinder and the mass of the concrete in the cylinder is recorded.
  • This mass is compared to the mass of fully compacted concrete in the same cylinder achieved with hand rodding or vibration.
  • Complete with the trowel and tamping bar 0-60 cms long X 16mm Dia.
