How do we measure the slump of concrete during casting? Is there a difference in slump value when casting concrete at a height of 50 meters or in high-rise buildings?

Question

Accepted Answer

Slump for casting of concrete is measured using a cone. Slump value may decrease as height increases in high rise buildings.

Slump is measured using a cone and the difference between the height of the cone and the height of the concrete after it settles is the slump value.
As height increases in high rise buildings, the pressure on the concrete increases, which may cause the slump value to decrease.
To maintain the desired slump value, additives such as plasticizers or superplasticizers may be used in the concrete mix.
Proper placement and compaction of the concrete can also help maintain the desired slump value.
