Description
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).
Application areas
- Where aggregates are susceptible to ASR
- With high/moderate alkali cement in geographic areas that could contribute to ASR
- Where there are external sources of alkali such as deicing salts, alkaline cleaners or marine environments
- Weather conditions (freezing and thawing/wetting and drying cycles)
- Traffic loading
- Critical structures
- Road, bridges, highways, parking garages
- Airport runways
- Water treatment facilities
- Dams, piers and docks
- Warehouses
Packaging
- 55 gallon drum
- 275 gallon tote
