MasterPozzolith 405 - Set retarding and water reducing concrete admixture


How does MasterPozzolith 405 work?

MasterPozzolith 405 is a ready to use, liquid admixture for producing quality concrete with consistent performance.
It reduces the quantity of mixing water required to produce concrete of a given workability with greater economy for a given strength. The retarding nature of the admixture also aids placing and finishing of concrete.

What makes MasterPozzolith 405 a unique solution?

MasterPozzolith 405 meets ASTM C494 Type B (Retarding) and Type D (water-reducing and retarding) admixtures. It does not contain chloride- based ingredients and will not initiate or promote corrosion of reinforcing steel in concrete.

How can you benefit from MasterPozzolith 405 ?

MasterPozzolith 405 used at optimum dosage enhances the performance of concrete providing the following special qualities:

  • Improved workability
  • Reduced segregation
  • Superior finishing characteristic
  • Controlled retardation depending on the rate of addition
  • Provides flexibility in scheduling of placing and finishing
  • Offset effects of too early hardening during extended delays between mixing and placing
  • Helps eliminate cold joints
  • Lower peak temperature and/or rate of temperature rise in mass concrete – reduces thermal cracking
