Version 2.0 is here

We've released a new version of the only concrete calculator that provides dosage rates for STRUX® 90/40 macro synthetic fibers. The app helps customers determine the right amount of fibers needed for each project, resulting in saved time. The updated app provides faster results, more detailed analysis with fewer inputs, a new cost analysis tool, with added transparency of the calculations. The new and improved macro fiber calculator also offers the option to auto-generate submittal packages in PDF format.

Mobile macro fiber calculator enhancements include:

  • Automatically export submittal packages as PDF
  • New resources section
  • Serviceability (temp and shrinkage crack control) and ultimate state (maximum moment carrying capacity) limit dosage rate calculations for slab on grade
  • Real-time calculations with easier conversion between imperial and metric unit systems
  • Cost analysis tool to compare savings using STRUX® macro synthetic fibers against traditional systems


The STRUX® concrete calculator recommends correct dosage rates for STRUX® 90/40 macro synthetic fibers, as a steel welded wire mesh (WWM) replacement in concrete installations.

The dosage rates provided by this calculator are backed by 20 years of research and development. This tool is free and open to use, but note that application rates depend on job-specific requirements which may vary from project to project.

App is free to download in the App Store and on Google Play.


A concrete calculator for macro synthetic fibers

Macro synthetic fibers are made to provide post-crack protection. They can help reduce construction time and labor costs over steel welded wire mesh, or traditional rebar reinforcement.

However, it's not always clear how much of these fibers to use. Well, now there's an app for that.
