what is workability

The ease with which a concrete mix can be handled from mixer to its compacted shape

• The amo unt of mechanical work , or energy , required to produce full compaction of concrete without segregation
• 3main characteristic

- Consistency
- Mobility
- Compactability

Consistency
- Describe the state of fresh concrete
- Measure of wetness or fluidity
Wet concrete are more workable than dry concrete

Mobility
- The ease which the mix can flow into and completely fill the formwork or mould

Compactability
- The ease with which a given mix can be fully compacted , all ( most of ) the trapped air being removed
