NS-7

Category: Specialty

USE

For production of non-shrink grout.

ADVANTAGES

• Increased compressive, shear and bond strength.
• Increased water retention.
• Reduced water requirements.
• Extended working life.
• Higher strengths may be achieved more economically.
• Easily adaptable to leaner mixes.
• Improves grout workability with no loss in strength.
• Expansion provides better contact with surrounding surfaces.
• Improves water-tightness by reducing cracks and cold joints.
• Improves cohesiveness and decreases bleeding and segregation.
• Reduced time and labor costs for placement.
• Allows ease of placement in difficult areas such as high density steel reinforcement.

DESCRIPTION

Fritz-Pak NS-7 is a ready-to-use dry powdered admixture for portland cement grouts. NS-7 is formulated to produce a more uniform and workable non-shrink grout with less water, improved flowability and extended set times. As a non-shrink additive, NS-7 will allow slow, controlled, in-place expansion prior to hardening. As a grout fluidifier, NS-7 will greatly enhance flowability allowing ease of placement with extended handling and set times. NS-7 also significantly reduces water requirements, 10 to 20 percent, yielding increased compressive and flexural strengths.

NS-7 is recommended for all types of high-lift portland cement grouting applications where improved non-shrink performance with increased flowability is desired. NS-7 does not contain calcium chloride, nitrites, nitrates or other potentially corrosive materials and is compatible with all standard grout additives.

COMPATIBILITY

NS-7 is compatible with all air-entraining admixtures, calcium chloride and other admixtures. When used with other admixtures, each one must be dispensed separately into the mix.
