During the hottest days on the job, the last thing you need is fast-setting concrete. Adding a set retarding admixture, like Standard Delay Set, helps make these days more bearable. This admixture is easily added to the truck at the plant, on the road, or at the job site. So you can keep your concrete fresh and workable whenever you need it.

Why Use a Set Retarding Admixture?

Fritz-Pak’s Standard Delay Set is a set retarding admixture formulated to overcome the increased hydration rate caused by warm temperatures. One bag delays the setting time of one yard of concrete by up to four hours. If you need additional time, you can add additional bags. Finally, keeping the concrete in its plastic state longer allows you the time you need to create a crack-free finish and protect your equipment if you get stuck in traffic.

Benefits of Standard Delay Set

Standard Delay Set comes packaged in our signature water-soluble bag, making it easy to dose wherever you need it. As a set retarding admixture, this product does not contain calcium chloride or other corrosive materials. While the initial dosage may change the slump and air content, the concrete will return to its original characteristics before the final set. Standard Delay is compatible with most other admixtures.

Will Standard Delayed Set affect my color?
o, it will not affect color of gray concrete. If using white concrete, use Fritz-Pak Plaster Delay Set.
Can I re-dose?
Yes. 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, Standard Delayed Set is compatible with most other admixtures.
Is it possible to mix for shorter times?
No. Standard Delayed Set must 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 Standard Delayed Set still work?
Yes. It is compatible with other admixtures.
If the concrete has started to set, can I use Standard Delayed Set to stop and reverse the setting?
No. Standard Delayed Set is used to delay the initial set. If setting has begun, Standard Delayed Set will not work.
How do I know when setting is starting to happen?
If you notice an increase in concrete temperature or a reduction in slump, concrete has started to set and Standard 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.
  • 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 Fritz-Pak inner bag for convenient use at the plant or job site


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.
