(57) A pre-stressed cast concrete structure (410) comprises embedded fibrous reinforcing tendons (118) in tension. The fibrous reinforcing tendons (118) each comprises a plurality of continuous non-metallic fibers extending substantially the entire length of the tendon (118). A system (100) for pre-stressing a cast concrete structure (410) includes a mold (112) for containing concrete, fibrous reinforcing tendons (118), chuck assemblies (200) associated with the reinforcing tendons (118) and a tensioning mechanism (110). When cured, the...
