The project initially specified steel fibres in the slab-on-ground concrete flooring of the plant. Steel fibres have been used in these applications for years. However, when Kevin Williams, TXI's Area Manager, was asked to supply concrete for the project, he knew there was an even better way to construct the manufacturing facility floor.

While the company had taken steps already to design slabs using macro fibres, eliminating welded wire mesh from their projects, steel fibres still posed disbursement and finishing problems for them. With the requirement of high, long-term performance at a cost-effective price, Kevin recommended STRUX® synthetic macro fibres to replace the steel fibres.

In fact, for this project, STRUX® 90/40 provided an opportunity for better performance, which immediately prompted Imperial Concrete, the concrete contractor on the project, to take the quote to the owner.

Unlike traditional "micro" fibre reinforcement, STRUX® 90/40 is specifically engineered to provide high, post crack-control performance in these applications. STRUX® 90/40 has been shown to reliably achieve average residual strength values in excess of 150 psi that can easily be batched and finished in the field and is easier and safer to use than these other types of secondary reinforcement.
