Fritz-Pak Mini Delayed Set is a dry powdered set retarder, packaged in a ready-to-use water-soluble bag. This product 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. It not contain calcium chloride, nitrates, nitrites, or other potentially corrosive materials and is compatible with all standard concrete admixtures.

Use a small bag of delay set for emergencies, small concrete batches, concrete pump hoppers, or wash water stabilization. Normally one bag will delay the set of 1 yard of concrete for 1 hour. For wash water stabilization one bag is used for overnight stabilization.

Will Mini Delayed Set affect my color?
No, it will not affect color of gray concrete. If using white concrete, use Fritz-Pak Plaster Delay Set.
Can I re-dose?
Yes. You can add more Mini Delayed Set if the initial concrete set has not started. You may re-dose up to three times.
What happens if I overdose the concrete?
Set time will be longer, but set will still occur.
Will it change the strength of my concrete?
Will it react with other admixtures?
No, Mini Delayed Set is compatible with most other admixtures.
Is it possible to mix for shorter times?
No. Mini Delayed Set needs to dissolve and be distributed evenly throughout the concrete. Short mixing times or mixing at slow speed may produce concrete with brown spots.
The concrete already has a retarder in it; will Mini Delayed Set still work?
Yes. Mini Delayed Set is compatible with other admixtures. See Product Bulletin #105 for details.
If the concrete has started to set, can I use Mini Delayed Set to stop and reverse the setting?
No. Mini Delayed Set is used to delay the initial set. If setting has already begun, Mini Delayed Set will not work.
How do I know when setting has begun?
If you notice an increase in concrete temperature or a reduction in slump, concrete has started to set and Mini Delayed Set may not be able to stop the setting process.
What is the difference between Mini and Standard Delayed Set?
The chemical used is exactly the same. The only difference is the size of the bag. Mini Delayed Set is an 8 oz. (½ lb.) bag, while Standard Delayed Set is a 2 lb. bag.
  • 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 Fritz-Pak inner bag for convenient use at the plant or job site


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.
