TamCem 9BFG


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 types of cement meeting recognised international standards. It complies with the requirements of EN 934-2 for water-reducing/set retarding admixtures.
