Procedure

  1. Place the flow table on a leveled surface
  2. Clean the top of the table and inner surface of the mould using a damp cloth.
  3. Place the slump cone centrally on the table.
  4. Fill the slump cone with concrete in two equal layers and tamp each layer 10 times with the help of wooden tamping bar.
  5. After filling the mould, the concrete is struck off flush with the upper edge of the slump cone an the free area of the table top cleaned off.
  6. Half a minute after striking off the concrete, slowly raise the cone vertically using the handles.
  7. Then raise the table top by handle and allow it to fall 15 times in 15 seconds. The concrete spreads itself out.
  8. Measure the diameter of spread concrete in two dimensions parallel to the table edges.

Results

The arithmetic mean of the two diameters shall be the measured  flow in millimeters.
