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:


  1. Water content
  2. Mix proportion
  3. Size of aggregate
  4. Shape of aggregate
  5. Surface texture of aggregate
  6. Grading of aggregate
  7. Use of admixtures
  8. Time of transportation
  9. Tempreture
  • Following tests are performed to determine workability of concrete.


  1. Slump test
  2. Compacting factor test
  3. Flow test
  4. Vee bee consistometer test
  5. Kelly bell test
