VARAPLAST EPG

PLASTICIZED EXPANDING GROUT ADMIXTURE

VARAPLAST EPG is supplied as a powder admixture. The material is a combination of a plasticising agent and a gas producing expansion medium. The plasticising agent allows the use of a reduced water / cement ratio with consequent increased strengths and durability. The expansive medium counteracts the natural settlement and plastic shrinkage of the grout and adds stability and cohesion. Sufficient restrained expansion is developed to ensure a high degree of interfacial contact. For Non - Shrink concrete mixes, the plasticization effect of VARAPLASTEPG is minimal, hence suitable superplasticiser, water reducer or retarder should be used when appropriate.

Uses

VARAPLAST EPG is an admixture for cementitious grouts where a reduced water / cement ratio and positive expansion are required. Applications include bed grouting, duct grouting, non-shrink concrete infilling & jointing.

ADVANTAGES

  • Powder form makes it easy to use in semi dry mixes.Gaseous expansion system compensates for plastic shrinkage and settlement in properly designed cementitious grout.
  • Reduced water / cement ratio in the grout mix ensures low permeability and long term durability in service.
  • Gives high grout fluidity with low water / cement ratio, thus making placement or injection of the grout easy.
  • No metallic iron content to corrode and cause staining and deterioration due to rust expansion in the grout.
  • Composition allows high early strength development in grouts, without the use of chlorides.

PACKAGING

VARAPLAST EPG is supplied in packs containing 24 x 250 g units and in 5 kg. and 25 kg. bags.
