What Is Concrete Slump? Hunker

Slump is a measurement of the workability or consistency of concrete. In other words, it measures how easy the concrete is to push, mold and smooth out. Accordingly, its slump rating indicates what construction application the concrete is good for. The higher the slump, the more workable the concrete.

Guide To Concrete Workability Concrete Slump

Concrete workability. One of the basic attributes of any concrete is its workability or "consistence", that is, how easy it is to push one way, pull the other, and float to a smooth level surface. Workability is largely determined by how fluid the concrete is. This is referred to as "Slump". Essentially, the more fluid the concrete, the higher the ...
