AS 1012.3.5:2015 pdf download.Methods of testing concrete Method 3.5: Determination of properties related to the consistency of

concrete-Slump flow,T5oo and J-ring test.

5.2 Rod

The rod used for striking ofT concrete from the top of the slump cone shall be a metal rod of 16 ±1 mm in diameter, approximately 600 mm long and having at least one end tapered for a distance of approximately 25 mm to a spherical shape having a radius of

approximately 5 mm.

5.3 Scoop

The scoop shall be made from non-absorbent material not readily attacked by cement paste of capacity not less than 1 L and suitable for taking increments of the concrete.

5.4 Base plate

The base plate shall he a non-reactive rigid flat plate with smooth, non-absorbent surface, at least 100 mm greater in diameter

than the maximum slump flow expected, marked with a circle of 200 mm diameter indicating the central location of the slump cone,

and a further concentric circle of 500 mm diameter (see Figures 2, 3 and 4). The base plate shall be constructed in a manner that

prevents distortion and does not have a deviation from flatness exceeding 3 mm at any point when a straight edge is placed between the centres of opposing sides.

NOTE: A suitable base plate should be at least 900 mm x 900 mm on which concrete can be placcd (see Figures 2, 3 and 4).
