MasterPozzolith® 80 (Formerly Pozzolith 80) 

MasterPozzolith 80 ready-to-use, liquid admixture is used for making more uniform and predictable quality concrete. MasterPozzolith 80 admixture meets ASTM C 494 requirements for Type A water-reducing, Type B, retarding, and Type D, retarding and water-reducing, admixtures.


  • Reduced water content required for a given workability
  • Controlled setting characteristics – normal or retarded


  • Increased compressive and flexural strength
  • Improved workability
  • Reduced segregation
  • Flexibility in the scheduling of placing and finishing operations
  • Offsets effects of early stiffening during extended delays between mixing and placing
  • Helps eliminate cold joints
  • Full-form deflection can take place (before concrete sets) in extended pours for bridge decks, cantilevers, nonshored structural elements, etc.
  • Peak temperature and/or rate of temperature rise lowered in mass concrete thereby reducing thermal cracking
