When it comes to delay set admixtures, few are as powerful or as versatile as Fritz-Pak’s Mini Delay Set. This dry, powdered admixture comes packaged in our signature water-soluble bags for ease of use whenever you need to slow down the set time of your concrete. Whether you’re on the road, at the plant, or at the job site, Mini Delay Set keeps your concrete fresh. One bag delays the setting time of one yard of concrete by up to an hour. Need more time? That’s easy, just add another bag.

Other Uses for Delay Set Admixtures

Delay Set Admixtures, such as Mini Delay, can be used for many different purposes other than slowing the hydration process for finishing reasons. For example, adding Mini Delay Set to concrete wash water in your drum stabilizes the water enough to be left in the drum. This allows you to return to the plant and use the water for the next load, even if that load isn’t scheduled until the next morning.

Besides being useful for ready-mixed drivers, delay set admixtures are helpful for concrete pump operators. Whenever a delay happens on the job, the pump operator has a choice to make. Either they shut the pump off and clean it out, or they recirculate the boom. Cleaning the pump means the equipment will have to be reset once the concrete arrives. And recirculating the boom increases the risk of a plug from hardened concrete – unless you add a bag of Mini Delay Set. This will keep the concrete plastic until the job is ready to start up again.

Benefits of Mini Delay Set

Fritz-Pak’s Mini Delay Set contains no calcium chloride or other corrosive materials that could compromise the integrity of the concrete. Like other delay set admixtures, Mini Delay Set may be redosed for extended set delay. Using this admixture won’t impact the overall strength of the concrete.

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.
