when we pour any material i.e, sand or gravel or any other material on ground it takes conical shape . Because, every particle has its own angle of internal friction. To maintain its angle of internal friction it takes the shape of the cone. so the reason why we prefer the slump test apoparatus in that shape.

∙ 13y agoThe slump cone is placed on a smooth, perfectly even, horizontal, rigid and non-absorbent surface.
It is then filled with fresh concrete sample in four layers, each approximately 1/ 4 of the height of the cone.
While filling the sample concrete in layers, each layer is tamped 25 times by the tamping rod taking care to distribute the strokes evenly over the cross section.
After the top layer has been tamped evenly, the excess concrete is struck off and leveled evenly with a trowel.
The slump cone is removed from the concrete immediately by raising it slowly and carefully in a vertical direction without causing any disturbance to the concrete just molded.
Allow the concrete to subside naturally due to gravity. This subsidence is referred as slump of concrete.
The difference in level between the height of the slump cone and that of the highest point of the subsided concrete is measured. This difference in height in mm is taken as Slump of Concrete.

∙ 11y agoIN Slump Test we have to provide a uniform base and it requires 4 times for compacting the concrete to fill the cone while without disturbing the bottom layer of concrete. but in other it is requred only to compact well to concrete with disturbed to bottom layer.which is good regarding the strength of concrete.

What is the importance of slump test in concrete work?
The importance of slump test in concrete work is to ensure consistency in the concrete. The test measures the workability of the concrete.
What is a concrete slump test?
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.
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.
What must be the slump value for different grade of concrete?
what is the slump value for M20 concrete
How do you increase slump in concrete?
If you are using a traditional concrete mix you can increase the slump by increasing the water you add.

What are advantages of slump test?
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.

What is the slump test normally used to evaluate?
the workability of a concrete mixture

Purpose of slump test for concrete?
To check the consistency of the concrete; to determine if the concrete flow smoothly into the shape of the formwork. It is a quick check to see if the concrete is suitable for use.
