Fritz-Pak FR-1 is a dry powdered concrete water reducer packaged in a patented ready-to-use water-soluble bag. It is formulated to produce a more uniform and workable mix with less water that yields stronger more durable concrete. This product is recommended for all types of concrete where improved concrete performance with a lower water-cement ratio and/or set retardation is desired. It does not contain calcium chloride or other potentially corrosive materials and is compatible with all standard concrete admixtures.

What is the shelf life of FR-1?
If stored properly, about 1-2 years. If the material ever seems hard or caked, do not use it. It will not break up in the mix.
What is the difference between a water reducer and a superplasticizer?
Both have the ability to chemically disperse cement, without the addition of water. That is why they are called water reducers. A water reducer has a limited capability in dispersion or water reduction, usually no more than 10% water reduction. A superplasticizer is a much stronger material and can reduce water content up to 40 %.
Will FR-1 discolor the concrete?
No, at the recommend dosage rate FR-1 will not discolor the concrete.
Does FR-1 affect the strength of the concrete?
Yes, if you use less water when adding FR-1, your concrete will be stronger. If your water content is not changed, strength is not changed.
Will it change the set time?
Yes. It is a slight retarder.
Will FR-1 effect the air content?
No.
What standards does it meet?
Meets ASTM C-494 Type D, AASHTO M-194 & CRD C-87.
Can I lower my cement content?
Yes. By lowering the water:cement ratio you can expect higher strengths. You can lower your cement content to lower your strength to meet your specification.
What are the best applications of FR-1?
FR-1 is extensively used as an ingredient in the manufacture of stuccos, bagged concrete, mortars, color hardeners and other cement based materials. Besides water reduction, it can also be used as a retarder for products used in warm weather conditions.
  • Increases compressive and flexural strengths
  • Higher strengths may be achieved more economically
  • Higher durability
  • Decreases segregation
  • Improved workability.
  • Extended set times may be achieved
  • Reduced water content for a given slump
  • FR-1 is packaged in water-soluble Fritz-Pak inner bag for convenient use at plant or job site, eliminating the need for admixture dispensers

Compatibility

FR-1 is compatible with all air-entraining admixtures, calcium chloride and other admixtures. When used with other admixtures, each admixture must be dispensed separately into the mix.
