When you need stronger, more durable concrete, adding a water reducer is the fastest and easiest way to adjust the mix. Fritz-Pak’s FR-1 lowers the water requirements of concrete, stucco, mortar, and other cementitious materials by up to 10%. While the product is not as powerful as our superplasticizers, it is still a great product to have around when you need to increase the strength and lower the water requirements of the mix.

Benefits of a Concrete Water Reducer

Adding a water reducer, such as FR-1, provides improved workability and durability of your concrete mix. These products create a higher-strength mix for more economical prices. In addition, Frtiz-Pak’s FR-1 includes a small amount of delay set. So it is an excellent choice for working with concrete in hot weather. Finally, FR-1 comes packaged in our signature water-soluble bag for ease of use.

How to Use a Concrete Water Reducer

FR-1 is available in three different sizes, including a 50lb bag for those extra big jobs. Once you have added the admixture to your concrete, it is very important that you mix it thoroughly. Improper mixing will cause unsatisfactory results.

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.
