Downloads

TamCem 9BFG is primarily a plasticiser/set retarder for TBM backfill grouts. Secondly TamCem 9BFG contains Normet’s unique dormant strength enhancing technology
to give early age strength boosts to grouts when accelerated using a set accelerator, such as TamShot 10SS.

TamCem 9BFG is a non-chloride liquid admixture formulated to give high water reduction, greater workability and extended open time. It is compatible with all cements meeting recognised international standards. It complies with the requirements of EN 934-2 for water reducing/set retarding admixtures.

Key Benefits
  • Contains a unique dormant accelerator to boost early strength of accelerated back-fill grouts
  • Good cohesion, no segregation and minimal bleed water with extremely high levels of workability
  • Controllable, long open time for enhanced placement and delivery control
  • Up to 50 % cost saving per m³ of grout. From a reduction in the cement and accelerator required as a like for like comparison in terms of strength
Typical Applications
  • Tunnelling and mining
  • TBM
  • Back-Fill grouts
