MasterSet AC 534

Accelerating admixture

Formerly: Pozzolith NC 534

How does MasterSet AC 534 work?

MasterSet AC 534 patented, ready-to-use, liquid admixture is formulated to accelerate time of setting and to increase early concrete strengths. MasterSet AC 534 admixture does not contain calcium chloride.

Recommended uses:

  • Reinforced, precast, pumped, flowable,
  • lightweight or normal weight concrete and shotcrete (wet mix)
  • Concrete placed on galvanized steel floor and roof systems which are left in place
  • Prestressed concrete
  • Fast-track concrete construction
  • Concrete subject to chloride ion constraints
  • 4x4 Concrete
  • Self-consolidating concrete (SCC)
  • Pervious concrete

What are the unique features of MasterSet AC 534?

  • Accelerated setting time across a wide range of temperatures
  • Increased early compressive and flexural strengths
  • Formulated to comply with ASTM C 494/C 494M Type C, accelerating admixture requirements

What are the benefits of MasterSet AC 534?

  • Earlier finishing of slabs — reduced labor costs
  • Reduced in-place concrete costs
  • Reduced or eliminated heating and protection time in cold weather
  • Earlier stripping and reuse of forms
  • Superior finishing characteristics for flatwork and cast surfaces
