Slump Cone Set (Cone+Base Plate+Rod)

Slump Cone with Tamping Rod and Base Plate

The test apparatus is carried out by filling the slump cone with freshly mixed concrete which is tamped with a steel rod in three layers. The concrete is leveled off with the top of the slump cone, the cone is removed and the slump of the sample is immediately measured.
To ensure that concrete achieves its maximum possible strength and yet retains its ease of placing on-site, it is essential that the design of the concrete mix, about the water-cement ratio and workability, is closely controlled.
