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.

The slump test is the most widely used device worldwide. In fact, the test is so well known that often the terms workability and slump are used interchangeably, even though they have different meanings. • Specifications are typically written in terms of slump. • The slump test is simple, rugged, and inexpensive to perform. Results are obtained immediately. • The results of the slump test can be converted to yield stress in fundamental units based on various analytical treatments and experimental studies of the slump test. • Compared to other commonly used concrete tests, such as for air content and compressive strength, the slump test provides acceptable precision.
Slump test is the most commonly used method of measuring workability of concretewhich can be employed either in laboratory or at site of work.ProcedureThe 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 levelbetween the height of the mould and that of the highest point of the subsided concrete ismeasured. This difference in height in mm is taken as Slump of Concrete.

The concrete slump test is used to measure an aspect of concrete. This test is used to measure the workable of concrete as well as its freshness and health.

A slump test is a method to measure the workability or consistency of concrete when it is fresh. It involves filling a cone-shaped mold with concrete, then removing the mold and measuring how much the concrete slumps or subsides. This test helps ensure that the concrete mix has the desired flowability for proper placement.
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.

compaction factor test is better than slump test,because compaction factor test should have own compaction wight,so correct value will be find out from compaction factor test.........
The slump test is suitable for site use because it is a simple and quick way to measure the workability of concrete, making it convenient for on-site applications. It requires minimal equipment and can be easily performed by construction workers without specialized training. The results of the slump test provide valuable information about the consistency of the concrete, helping workers make real-time adjustments to achieve the desired quality of the concrete mix.
