Fields of application

PANTAQUICK^® RSM 935 is a high performing admixture for activating the setting in mortars or slurries used in injections. The main application field of PANTAQUICK^® RSM 935 is for the injection of annular grouting behind the segmental concrete lining of TBM-constructions. PANTAQUICK^® RSM 935 activates the cement setting by re-starting the hydration process. The accelerating admixture provides the following benefits:
>  Ensures a very fast setting
>  Generates high early strength
>  Creates low viscosity grout
>  Supports stability of grout
>  Allows ideal injection conditions
>  Simple application
>  Enables rapid work process
>  Enhanced mechanical performance development
PANTAQUICK^® RSM 935 provides the ability to control the hydration process over several days. This ability allows flexible handling with construction halts and time schedule changes.

Working principle

PANTAQUICK^® RSM 935 is the second component of Ha-Be’s two component hydration control system. In order to create a high performing grouting, it is recommended to use the accelerating admixture in combination with one of the PANTARHIT^® RSM superplasticizers. The two component system allows the production of durable, powerful and stable grouting perfectly geared to the needs of TBM constructions.
