Expanding Grout Admixture (For Mortar and Concrete)

CONSOL EXPANDER is a plasticized expanding grout admixture is supplied as a powder. This product is an expansion system which compensates for plastic shrinkage and settlement in cementitious grouts and concrete. It contains a water-reducing agent which increases the workability of the mix with a reduced water content. Applications include bed grouting, duct grouting, non-shrink infilling and jointing. By introducing micro bubbles into the mix, it produces wet volume expansion and increased fluidity without segregation.

CONSOL EXPANDER is used to increased cohesion in cement grouts and is suitable for use in the grouting of:

  • Pre-stressed cable ducts
  • Rock and soil anchoring
  • Bearing plates
  • Pre-placed aggregates
  • Tunnels lining
  • Pre-cast concrete elements
  • Tilt construction wall panels
  • Crack injection.


  • A cement plasticizing and water reducing agent to improve the free flowing properties of the grout at low water/cement ratios.
  • An expanding agent that increases the volume of the grout or concrete which in turn eliminates shrinkage and settlement.
  • Gives grout high fluidity with low water/cement ratio, thus making placement or injection of the grout easy.
  • Reduced water/cement ratio mixes in the grout mix ensures low permeability and long term durability in service.
