MasterSet R 300

MasterSet R 300 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.

What are the unique features of MasterSet R 300?

• Reduced water content required for a given workability
• Retarded setting characteristics
• Improved workability
• Reduced segregation
• Superior finishing characteristics for flatwork and cast surfaces
• Moderate to extended retardation – depending on the dosage rate
• Full-form deflection can take place (before concrete sets) in extended pours for bridge decks, cantilevers, non-shored structural elements, etc
• Meets ASTM C 494/C 494M requirements for Type B, retarding, and Type D, water-reducing and retarding, admixtures

What are the benefits of MasterSet R 300?

• Flexibility in scheduling of placing and finishing operations
• Offsets effects of early concrete 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
• Increased compressive and flexural strengths​
