How to Use This Calculator

Enter the total concrete volume in cubic yards for the placement.
Select the fiber type: 1 for synthetic micro (crack control, ~1.5 lbs/yd³), 2 for steel (structural, ~50 lbs/yd³), or 3 for macro synthetic (both).
Enter the dosage in lbs/yd³ per manufacturer recommendations or your engineer's specification.
Check Total Fiber (lbs) and Bags Needed to prepare your material order.
Compare Estimated Cost to the Savings vs WWF output to see whether fiber is more economical than welded wire fabric.
Confirm Dosage Adequate (1=Yes) to ensure the specified rate meets minimum recommendations for your fiber type.
