Slump Test Apparatus
Ref. Standards IS:7320, BS:1881, ASTM C 143,AASHTO T119
The slump cone is filled with freshly mixed concrete and is tamped with a tamping bar in three or four layers. The top of the concrete is levelled off with the top of the slump cone, the cone is lifted vertically up and the slump of the sample is immediately measured.

• Base has cleats on its underside to help dig into the ground surface.
• Positive clamping of slump cone to the base while filling and rodding the concrete
• A combination swivel carrying handle also doubles as the datum making the conventional and somewhat awkward measuring procedure of using a foot rule and a datum bar, a thing of the past
