Abstract
Methods of forming cast prestressed concrete elements and structures include a non-corrosive reinforcing element being formed of a plurality of substantially parallel continuous filaments embedded in a matrix of thermosetting resin. These reinforcing elements are tensioned, then concrete cast about the elements is permitted to harden and the tension transferred to the now-hardened concrete in order to prestress the same. The resulting concrete elements and structures have high resistance to alkali induced corrosion of the prestressing elements.
