Why hooked ends are used
Hooked ends increase mechanical anchorage and can support residual load capacity after cracking when the fiber and dosage are correctly designed and tested.
Shotcrete compatibility
Fiber length, aspect ratio, aggregate size, pumping equipment and nozzle performance must be considered together. Excessively difficult mixing or pumping can undermine field results.
Project testing
Tunnel specifications commonly define performance tests and acceptance criteria. Confirm the exact standard, specimen method and required residual values before supply.
RFQ checklist
Provide the shotcrete mix, equipment, fiber geometry, proposed dosage, monthly consumption, packaging preference and delivery location.
