Workability and Concrete Slump Ranges

The slump test is basically a measure of the consistency of fresh concrete or its workability. Fresh concrete is placed in to a hollow steel cone known as a slump cone or Abrams cone and using the following procedure, the final slump can be determined. The slump cone mould should be thoroughly cleaned and coated with a thin film of oil.
