1. A structural member for reinforcing a product formed of a hardenable structural material after hardening of the material, said structural member being in the form of a reinforcing grid including first and second types of fibers in which one of said types of fibers has a higher strength sufficient to reinforce the hardenable material after hardening and a higher resistance to degradation in the hardenable material than the other type of fibers and the other of said types of fibers is less expensive than the one type of fibers to reduce the cost of said structural member, said reinforcing grid comprising:

  • a set of warp strands wherein at least some of said warp strands are spaced apart, and at least some of said warp strands are formed of fibers of one of said first or second type of fibers;

    a set of weft strands wherein at least some of the strands are spaced apart and disposed at substantially right angles to said set of warp strands to define an open structure through which the hardenable material can pass before hardening, and at least some of said weft strands are formed of the other of said first or second types of fibers;

    whereby, said gridwork is partially formed of fibers of the first type which will continue to reinforce the hardened material in the event the fibers of the second type become corroded in the hardened material.
