RASIR®
To mitigate and control alkali-silica reactivity (ASR) in concrete
RASIR® is a liquid admixture formulated to mitigate and control Alkali-Silica Reaction (ASR) in concrete. It is particularly effective when using potentially reactive aggregates or sand with high or moderate-alkali cement, or in environments with external sources of alkalis. RASIR® is a 30% lithium nitrate solution.
Key Benefits:
- ASR Mitigation: Effectively controls ASR in concrete, enhancing durability.
- Versatile Application: Suitable for use with high/moderate alkali cement and in geographic areas prone to ASR.
- Protection Against External Alkalies: Provides resistance to deicing salts, alkaline cleaners, and marine environments.
RASIR® is ideal for use in various critical structures and environments, including:
- Roads, Bridges, and Highways
- Parking Garages
- Airport Runways
- Water Treatment Facilities
- Dams, Piers, and Docks
- Warehouses
Environmental and Operational Conditions:
- Effective in weather conditions involving freezing and thawing, as well as wetting and drying cycles.
- Suitable for structures subjected to heavy traffic loading.
RASIR®
RASIR® is a liquid admixture that can mitigate and control ASR in concrete when using potentially reactive aggregates or sand with high or moderate-alkali cement or where there are sources of external alkalies. RASIR® is a 30% lithium nitrate solution. RASIR® weighs approximately 10 lbs/gal (1.2 kg/L).
