PANTARHIT^® RSM 333

Admixture for conditioning annular grout mixes used in TBM tunnelling

Item No. 0655/E

FIELDS OF APPLICATION

PANTARHIT^® RSM 333 is a high performance admixture especially designed for conditioning annular grout mixes injected behind the segmental concrete lining of TBM constructions.

WORKING PRINCIPLE

PANTARHIT^® RSM 333 disperses annular grout mixes while retarding the initial and final setting. Therefore the admixture is able to allow reductions in the water content or to improve the workability without the addition of extra water.

PANTARHIT^® RSM 200 delays the hydration process and extends the workability time of annular grout mixes purposefully.

DOSAGE | APPLICATION QUANTITY

Due to the different compositions of annular grout mixes, the necessary dosage quantity varies and needs to be determined in field trials.
