WHAT IS WORKABILITY OF CONCRETE
WORKABILITY OF CONCRETE
- Fresh concrete or plastic concrete is freshly mixed material which can be moulded into any desired shape
- The diverse requirements of partial properties of concrete like mixability, stability, transportability, placebility, mobility, compactability and finishability are collectively reffered as a workability of concrete. So it is a composite property.
- Factors affecting workability of concrete:
- Water content
- Mix proportion
- Size of aggregate
- Shape of aggregate
- Surface texture of aggregate
- Grading of aggregate
- Use of admixtures
- Time of transportation
- Tempreture
- Following tests are performed to determine workability of concrete.
- Slump test
- Compacting factor test
- Flow test
- Vee bee consistometer test
- Kelly bell test
It is truly a well-researched content and excellent wording. I got so engaged in this material that I couldn’t wait to read. I am impressed with your work and skill. Thanks. concrete and fencing contractors
