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 leveled off with the top of the slump cone, the cone is lifted vertically up and the slump of the sample is immediately measured. Conforming to BIS 7320. This apparatus used for the determination of workability of concrete where nominal size of aggregate does not exceed 38mm. The apparatus comprises of a slump cone with foot pieces fitted on a base with wing bolts. A Swivel carrying handle fitted with the base also serves as a datem for measuring the slump, when moved in to vertical position perpendicular to the base.
A Swivel carrying handle fitted with the base also serves as a datem for measuring the slump, when moved in to vertical position perpendicular to the base. A graduated tamping rod is used both for compacting the specimen as well as measuring the slump of concrete.
