RASIR®

Admixture to Control Alkali-Silica Reaction in Concrete

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
  • Bulk
