FR-1 FAQ

Q. What is the difference between a water reducer and a superplasticizer?

A. 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%.

Q. Will FR-1 discolor the concrete?

A. No, at the recommend dosage rate FR-1 will not discolor the concrete

Q. Does FR-1 affect the strength of the concrete?

A. 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.

Q. Will it change the set time?

A. Yes. It is a slight retarder.

Q. Will FR-1 effect the air content?

A. No.

Q. Can I lower my cement content?

A. 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.

Q. What are the best applications of FR-1?

A. 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.
