Fields of application

PANTARHIT^® RSM 100 (VZ) is a high performance admixture especially designed to control the setting of annular grout mixes for injection behind segmental tunnel linings. PANTARHIT^® RSM 100 (VZ) retards the initial and final setting of annular grout mixes and allows a purposeful extension of workability time. Additionally, the special formulation of the powerful admixture is able to provide a stabilising effect. These features enable an extended storability of the annular grout in the pumping lines and grout agitator tanks on the TBM.

The application of PANTARHIT^® RSM 100 (VZ) enables increasing the compressive, tensile and flexural strength of annular grout mixes. The special formulation of PANTARHIT^® RSM 100 (VZ) allows the application of the product as conditioning admixture in one or two component grouting systems.

Working principle

PANTARHIT^® RSM 100 (VZ) delays the hydration process and extends the workability time of annular grout mixes purposefully.
