Shrinkage Compensating Admixture

CONEX-NF is a concentrated powdered admixture used for 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-NF is an expansive Type G component, which produces a calcium hydroxide platelet crystal system, as specified in ACI 223. CONEX-NF contains no added chlorides or chemicals known to promote the corrosion of steel.

Features & Benefits

  • Expansion characteristics of CONEX-NF allow for net shrinkage reduction for concrete..
  • Minimal slump loss.
  • May be used in conjunction with other Euclid Chemical admixtures.
  • Will not affect the mechanical strengths.
  • Compatible with the majority of Portland cements.
  • Minimal effect to air content, set time, or other characteristics of fresh concrete.
  • 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.
