MasterSet R 200
Set retarding admixture for concrete
How does MasterSet R 200 work?
MasterSet R 200 is a ready-to-use, liquid admixture for producing more uniform and predictable quality concrete. Placing and finishing requirements are facilitated because this admixture retards setting times, increases compressive strength, reduces water content required for given workability and retards the setting characteristics of concrete.
What is MasterSet R 200 used for?
MasterSet R 200 admixture is recommended for use in all types of concrete where moderate to extended retardation of set and improved performance are desired. This admixture improves pumped concrete, shotcrete (wet-mix), and conventionally placed concrete. It improves plain, reinforced, precast, prestressed, lightweight or normal weight concrete.
MasterSet R 200 admixture can be used with air-entraining cements and with air-entraining admixtures complying with BS EN934-2 specifications - including those manufactured by BASF plc, when air-entrained concrete is desired. On its own, MasterSet R 200 admixture does not entrain air.
MasterSet R 200 admixture can be used in white or coloured concrete and in architectural concrete.
What are the benefits of MasterSet R 200?
The set retarding characteristics of MasterSet R 200 admixture aid in the production of concrete with the following special qualities:
- Improved workability.
- Reduced segregation.
- Superior finishing characteristics for flatwork and cast surfaces.
- Controlled retardation - depending on the addition rate.
- Provides flexibility in scheduling of placing and finishing operations.
- Offsets the effects of too early hardening during extended delays between mixing and placing.
- Helps eliminate cold joints.
- Allows for dead-load deflection to take place (before concrete sets) in extended pours for bridge decks, cantilevers, non-shored structural elements, etc.
- Lowers peak temperature and/or rate of temperature rise in mass concrete - reduces thermal cracking.
- Effective as a single admixture or as a component in an Admixture system.
