How Is Concrete Slump Measured?

 

The slump of the concrete is measured by measuring the distance from the top of the slumped concrete to the level of the top of the slump cone.

How Is Concrete Slump Measured?

Concrete slump is a measure of the consistency of concrete. It is determined by how much the concrete mixture falls or deforms when it is first placed in the mold.

The slump test is simple and easy to perform, and it provides a good indication of the workability of the concrete. The test is often used to adjust the water content of the concrete mixture.

The slump test is performed by filling a mold with the concrete mixture. The mold is then lifted and allowed to fall onto a surface. The amount of fall or deformation is then measured.

The concrete is considered to be of good quality if it has a slump of 3 to 5 inches (7.6 to 12.7 cm). The slump test is a good indicator of the workability of the concrete, but it is not a perfect measure.

The test is affected by the amount of water in the concrete mixture, the type of aggregate, the amount of cement, and the temperature. The test is also affected by the way the concrete is placed in the mold and the way the mold is lifted.
