CONCRETE 101

Slump is a measure of concrete consistency or fluidity. Consistency is the ability of freshly mixed concrete to flow. For given proportions of cement and aggregates (without admixtures), the higher the slump, the wetter the mix. Four-inch (4") slump is very common

Concrete slump test - Wikipedia

The concrete slump test measures the consistency of fresh concrete before it sets. It is performed to check the workability of freshly made concrete, and therefore the ease with which concrete flows. It can also be used as an indicator of an improperly mixed batch.

What Is Concrete Slump? | Hunker

Definition. 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.

The Effect of Aggregate Properties on Concrete

The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete.

Guide To Concrete Workability | Concrete Slump | …

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".
