What is workability of concrete?

The workability of concrete defines the properties of a fresh concrete mixture. It defines how a new fresh concrete can be mixed, placed, consolidated, and finished without segregation. It is a very important property of concrete as it tells about the strength. It also affects the quality, appearance, finishing operation, and also the cost of labor.

Heavily reinforced section and thin inaccessible section demands more workability rather than a mass concrete body. It determines the work needed to get a freshly mixed concrete without disturbing homogeneity.

In terms of compaction, workability can define the amount of useful work required to give full compaction.
