What is slump?

Slump is a measure of consistency or wetness of freshly mixed concrete.

  • Dry Slump (20 to 50mm)
    (giving very low shrinkages due to reduced water content, difficult to work with)
  • Normal Slump (60 to 100mm)
    (giving suitable workability for standard class applications)
  • High Slump (110 to 160mm)
    (for improved pumpability, for ease of placement, labor savings - will affect final strength of concrete)
