In the field, we will conduct tests for almost all materials. Those tests are not accurate and don’t have any high accuracy. The slump test is not an exception.
A slump test is being done at the site to find out the workability and consistency of the fresh concrete. It does not give accurate results but it is useful to detect the uniformity of concrete mix.
Since its main apparatus is a conical shape mold it is called a Slump Cone Test.
Ideal Value of Slump for works (Chart)
As mentioned above to find out the workability of fresh concrete.
Most of the concrete defects such as shrinkage, crazing are directly related to the water-cement ratio. Using the slump test, it is possible to identify the required slump for the specific work and can avoid unnecessary defects without waiting for the detailed lab tests such as
The concrete slump test will be conducted at the site as per IS 1199. Let’s start with the test procedure.
All the apparatus should be free from moisture or any other affluent and also it should be in dry condition.
Concrete slump results can be classified into 3 types such as
What is a zero slump concrete?
When the concrete not falling down on the pan after removing the mould is called zero slump. It states that the concrete was too stiff and had less water-cement ratio.

Amazing thank you
