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.
