Set Retarders & Accelerators

Standard Delay Set

Standard Delayed Set is a dry powdered admixture, packaged in a ready-to-use water soluble bag. It is formulated to extend the setting time of concrete while improving concrete quality. It does not contain any calcium chloride or other potentially corrosive materials and is compatible with all standard concrete admixtures.

Advantages

• Keeps concrete in a plastic state for re-use or extended delivery time requirements.
• Fewer environmental problems associated with the disposal of waste concrete.
• Saves labor, equipment and freight cost by eliminating disposal of waste concrete.
• Eliminates the need for expensive reclaiming or recycler units with high maintenance costs.
• Improves concrete workability.
• Allows wash water stabilization for extended periods of time.
• No need for admixture dispensers because Standard Delayed Set is packaged in water-soluble inner bag for convenient use at the plant or job site.

Compatibility

Standard Delayed Set 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.

Mini Delay Set

Mini Delayed Set is a dry powdered admixture, packaged in a ready-to-use water soluble bag. Mini Delayed Set is designed for stabilizing residual concrete wash water or extending the setting time of concrete while improving concrete quality. Wash water or concrete, treated with the Mini Delayed Set, will be stabilized and may be reused after extended time periods. Concrete produced with stabilized wash water will result in performance characteristics equal to or superior to reference concrete. Mini Delayed Set does not contain calcium chloride, nitrates, nitrites or other potentially corrosive materials and is compatible with all standard concrete admixtures.

Advantages

• One bag typically retards the set of one yard of concrete for one hour.
• Concrete may be kept in a plastic state for reuse or extended delivery times.
• Saves labor, equipment and freight costs by eliminating disposal of waste concrete.
• No need for expensive reclaimer/recycler units and their high maintenance costs.
• Reduces labor costs required for chipping set concrete out of mixer drums when used after each load.
• Reduces the amount of water required for wash down.
• Decreases environmental problems due to the disposal of waste concrete and residual concrete wash water.
• No need for admixture dispensers because Mini Delayed Set is packaged in a patented water-soluble inner bag for convenient use at the plant or job site.

Compatibility

Mini Delayed Set 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.

Non-Chloride Accelerator

NCA is a non-chloride accelerator in powdered form. It is packaged in water soluble bags for easy addition to concrete ready mix trucks. It shortens set times while increasing early compressive strength. NCA does not contain calcium chloride or any other materials that promote corrosion in steel or efflorescence in concrete. Unlike some other non-chloride accelerators, such as those containing calcium nitrite, NCA is not hazardous. No special handling, storage or transportation expense is required.

Advantages

• Speeds up concrete set time.
• Provides higher early strength.
• NCA does not promote steel corrosion.
• Dosage can be increased for faster acceleration.
• The material does not require heated warehousing.
• Can be used in all weather.
• Acceleration is dependant on dosage used.
• The need for protection and heating of concrete in cold climates is reduced or eliminated.
• Allows faster reuse and stripping of forms.
• Suitable for all types of concrete.
• NCA is packaged in a patented water-soluble

Compatibility

Fritz-Pak NCA is compatible with most concrete admixtures. When used with other admixtures, each one should be dispensed separately into the mix. Effectiveness of NCA is dependent on the proportion of C3A to SO3 in the cement. Higher acceleration will be obtained in cements with ratios greater than 4.0. In general, higher accelerations will be obtained in mixes with Type I, III or white cement.
