PROCEDURE OF TEST:
• Prepare a leveled surface and place the flow table on the surface.
• Use a damp cloth to clean the top of the table and the inner surface of the mould.
• Place the slump cone shaped mould on the table.
• Fill the cone with fresh concrete in two equal layers and start tamping each layer 10 times using the wooden tamping bar.
• After tamping the concrete is then struck off flush with the upper edge of the cone and the free area of the top of the table is cleaned off.
• After half a minute of striking off, lift the cone vertically.
• Then raise the table top by the handle and allow it to fall 15 times in 15 seconds. The concrete spreads itself out.
• Measure the diameter of spread concrete in two dimensions parallel to the table edges.
RESULT:
The arithmetic mean of the two diameters shall be the measured flow in millimeters.
