Frequently Asked Questions
What is the correct dosage rate?
1 bag (500g) per cubic metre of concrete is the standard dosage for plastic shrinkage crack control. Consult your engineer for structural applications.
Does the bag need to be opened?
No. The pulpable bag dissolves completely in the mixer — simply toss it in whole.
Is this product compatible with admixtures?
Yes. PP fiber is chemically inert and compatible with standard concrete admixtures including water reducers, accelerators, and retarders.
