MasterSet® R 961 (Formerly POZZOLITH 961 R) 

MasterSet R 961 ready-to-use, liquid admixture is used for making more uniform and predictable high-performance concrete while retarding its setting time to facilitate placing and finishing operations. It meets ASTM C 494/C 494M requirements for Type B, retarding, and Type D, water-reducing and retarding, admixtures.

Features

  • Reduced water content required for a given workability
  • Retarded setting characteristics
  • Improved workability
  • Reduced segregation
  • Superior finishing characteristics for flatwork and cast surfaces
  • Increased compressive and flexural strength
  • Full-form deflection can take place (before concrete sets) in extended pours for bridge decks, cantilevers, nonshored structural elements, etc.

Benefits

  • Flexibility in the scheduling of placing and finishing operations
  • Minimizes premature hardening during extended delays between mixing and placing
  • Helps eliminate cold joints
  • Peak temperature and/or rate of temperature rise in mass concrete lowered thereby reducing thermal cracking
