Concrete SlumpTest
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.
  • The slump cone mould is then placed on a smooth, flat, rigid and non-absorbent surface.
  • The slump cone mould is then filled with four layers of the concrete mix, with each layer being tamped with a standard tamping rod.
  • Once the mould has been filled the concrete mixture is levelled with the top of the cone.
  • The slump cone is carefully lifted upwards, taking care not to disturb the concrete contained within.
  • Once the concrete subsides the difference in height to the original height of the slump cone is measured as the slump and slump flow.
