Abstract:
1. A reinforced concrete structure comprising a reinforcement embedded within cured concrete, wherein the reinforcement is in the form of primary closed loops disposed in a given direction with a first loop end followed by a second loop end in the given direction, each primary closed loop embedded within the cured concrete comprising at least two elongated string sections, parallel and distanced apart from each other, ends of the at least two elongated string sections being interconnected by a curved arced transition forming the first and second loop ends, the first and second loop ends completely embedded within the cured concrete and imposing compressive forces on the surrounding concrete as the concrete structure is subjected to external loads and forces, and wherein the primary closed loops are positioned to run in the given direction substantially end-to-end but with an overlap of the second loop end of a first one of the primary closed loops overlapping with the first loop end of a second one of the primary loops to form a closed internal secondary loop exposed to compressive forces from the primary closed loops caused by tensional forces acting in the at least two elongated string sections as the concrete structure is subjected to the external forces and loads, and each of the at least two elongated string sections formed of a number of single fiber filaments of carbon or basalt, which is wound to a continuous string by repeated windings of the single fiber filaments and embedded in a matrix, thereby providing a composite fiber string.
