TamCem 67 is a new generation superplasticiser for high early strength concrete. It contains state-of-the-art polycarboxylate ether polymers and is specially formulated to give high water reduction, enhanced workability and offers superior early age strength development. TamCem 67 specially designed for precast concrete applications. It is a non-chloride liquid admixture which has been formulated to comply with the requirements of EN 934-2 and ASTM C 494 for Type F high range water reducing/superplasticising admixtures. TamCem 67 is compatible with all cements meeting recognised international standards.

TamCem 67 is based on versatile polycarboxylate co-polymer technology. Its unique long chain molecular structure enhances the dispersion of cement particles, by means of steric hindrance, whereas conventional SNF and SMF based superplasticisers, will only undergo less powerful electrostatic repulsion. In addition to the polycarboxylate co-polymers, TamCem 67 also contains components capable of increasing the rate of early age hardening of the concrete at ambient and low temperatures.

Key Benefits
  • High water reduction which provides high early and ultimate strengths, low permeability and high durability of the concrete
  • High flowability provides easy placement and compaction
  • Excellent cohesion, zero segregation and minimal bleed water with extremely high levels of concrete workability.
  • High early age strength can be obtained even at low temperatures
  • Can partly replace steam curing at low water/cement ratios
  • High elastic modulus, low shrinkage and creep are achieveable using graded coarse and fine aggregates.
  • Superior finishes with reduced honeycombing
Typical Applications
  • Precast concrete
  • High performance concrete
  • Improving mixing efficiency during large pour
  • Highly durable concrete
  • High strength concrete
  • Self-compacting concrete as well as low slump concrete
