Shrinkage Compensating Admixture

CONEX® is a powdered admixture used for the compensation and total overall reduction of net shrinkage for Portland Cement concrete. Its functional mechanism is based on the formation of an expansive component. CONEX® is an expansive Type G component, which produces a calcium hydroxide platelet crystal system, as specified in ACI 223.

Features & Benefits

  • The expansion characteristics of CONEX® allow for net shrinkage reduction for concrete
  • Use of this admixture does not cause any slump loss and may be used in conjunction with other Euclid Chemical admixtures
  • Will not affect the mechanical strengths
  • It is compatible with the majority of Portland cements
  • CONEX® does not affect the air content, set time, or other characteristics of fresh concrete
  • The addition of CONEX® should not adversely affect freeze-thaw and salt scaling resistances given that an adequate air void system is provided
  • Expansion process is not through ettringite formation

Applications

  • Flatwork concrete
  • Bridge decks
  • Parking structures
  • Interior/Exterior
  • Arena/Artificial skating rinks
  • Walls/Parapets
  • Storage tanks
  • Watertight construction
  • Toppings
  • Piers

Specifications / Compliances

  • Meets ASTM C494 Type S admixture
  • ANSI/NSF STD 61 registered
