  • The mould is placed on a smooth, horizontal,rigid and non-absorbant surface The mould is then filled in four layers, each approximately 1/ 4 of the height of the mould.
  • Each layer istamped 25 times by the tamping rod taking Slump Test Apparatus care to distribute the strokes evenly over the cross section.
  • After the top layer has been rodded, the concrete is struck off level with a trowel and tamping rod. The mould is removed from the concrete immediately by raising it slowly and carefully in a vertical direction. This allows theconcrete to subside. This subsidence is referred as slump of concrete.
  • The difference in level between the height of the mould and that of the highest point of the subsided concrete is measured. This difference in height in mm is taken as Slump of Concrete.

What does a slump mean in concrete?

The term slump used in concrete means the thickness or thinness of the concrete. The slump is measured by filling a 12" cylinder up with concrete, then flipping it over and pulling the cylinder up. The distance the concrete "slumps" down from the top of the cylinder is the slump for that concrete. For example, if the concrete falls 6" from the top of the cylinder, that concrete is on a 6" slump.

Why do you need slump test?

The slump test is essential for assessing the workability and consistency of fresh concrete. It helps determine how easily the concrete can be mixed, placed, and finished, which is crucial for achieving the desired strength and durability. By measuring the slump, engineers can ensure that the concrete mixture meets the specifications required for the project and can make adjustments if necessary to achieve optimal performance.
