RussTech Inc Superflo 443

Superflo 443 is a high molecular weight, high-range water-reducing admixture formulated to produce high slump concrete at lower water to cementitious ratios. Concrete produced with Superflo 443 shows increased flowability while maintaining early and ultimate compressive and flexural strengths. Superflo 443 is specially formulated to retain slump for extended periods of time, enabling it to be dosed at the batch plant or job site throughout the entire dosage range with normal set times.

Product Type: Superplasticizer

Features: Cost Effective, Freeze/Thaw Stability, Good Cohesion, Good Compressive Strength, Good Flexural Modulus, High Durability, High Elasticity, High Flowability, High Molecular Weight, High Strength, Low Creep, Low Permeability, Low Shrinkage

Product Highlights

Low slump concrete dosed with Superflo 443 becomes high slump concrete at the job site assuring good consolidation of concrete around reinforcing steel with little or no vibration.

Advantages
  • Cohesive and non-segregating
  • Consistent and controlled time of set throughout entire dosage range
  • Accelerated construction methods resulting in earlier completion dates
  • Reduced contractor placement costs
  • Higher and earlier ultimate strengths
  • Better flowing concrete with minimal bleed water
  • Improved durability with lower permeability
  • Higher modulus of elasticity
  • Increased resistance to freeze thaw cycleslower water to cement ratio for a given slump
  • Maximum slump retention for a superplasticizer
  • Reduced shrinkage and creep
  • Improved resistance to sulfate attack

Applications & Uses

Compatible Substrates & Surfaces
Uses

Superflo 443 is recommended for use in concrete where higher flowability and increased early and ultimate strengths are required.

Superflo 443 allows the contractor or superintendent to place concrete with improved and increased strength while lowering placement labor costs.

Compatibility

Superflo 443 is compatible with all types of Portland cement, class C and F fly ash, silica fume, calcium chloride, fibers and approved air entraining, accelerating, retarding, and water reducing admixtures. Superflo 443 can be used in white, colored, and architectural concrete. For best results, each admixture must be dispensed separately into the concrete mix.

Dosage Rate

SUPERFLO 443 is recommended for use at a dosage rate of 10 to 26 ounces per 100 pounds (652 mL to 1695 mL per 100 kg) of cementitious material.
Because local job conditions vary, contact your local RussTech technical service representative for further assistance if using outside recommended dosage ranges.
