Disclosed is a structure of a matrix, reinforced with a plurality of polymeric fibers protruding from at least a portion of the structure surface, the fibers being capable of endowing (attributing) the at least a portion of the surfacewith biological or chemical resistance. In some embodiments, the polymeric fibers, as further discussed hereinbelow, contain or are coated with at least one biological or chemical agent which further contributes to the endowment of biological or chemical resistance.

1. A structure comprising: a matrix including a surface, the matrix reinforced with a plurality of polymeric fibers, the polymeric fibers including at least one a biological agent or a chemical agent, the polymeric fibers protruding from at least a portion of the surface, the polymeric fibers being capable of endowing the at least a portion of the surface with biological or chemical resistance, and the fiber content of the polymeric fibers protruding from the surface is 10 to 100 fibers per square millimeter. 2. The structure according to claim 1, wherein the biological agent is a biocide reactive against microorganism growth and is incorporated into the fibers. 3. The structure according to claim 2, wherein said biocide is a quorum sensing antagonist capable of disturbing biofilm formation or bacteria production sequence. 4. The structure according to claim 3, wherein the amount of the quorum antagonist in the fibers is between 0.001% and 5.00% wt. 5. A structure comprising: a matrix including a surface, the matrix includes concrete and is reinforced with a plurality of polymeric fibers protruding from at least a portion of the surface, the polymeric fibers including at least one biological agent or chemical agent, and being capable of endowing the at least a portion of the surface with biological or chemical resistance, and the fiber content of the polymeric fibers protruding from the surface is 10 to 100 fibers per square millimeter. 6. The structure according to claim 5, wherein the volume fraction of the fibers in the concrete at the surface of the structure is within the range of 0.025% to 25%. 7. A process for manufacturing a structure reinforced with a plurality of polymeric fibers protruding from at least a portion of its surface, the fibers being capable of endowing the at least a portion of the surface with biological or chemical resistance, the process comprising: obtaining a mixture of a desired matrix material and a plurality of polymeric fibers containing or being coated with a biological or chemical agent; forming a structure of said mixture; and, treating at least a portion of the structure surface to expose the fibers' ends; to thereby obtain a structure including a matrix with a plurality of polymeric fibers disposed therein and protruding from at least a portion of matrix at the structure surface, the fibers including at least one biological or chemical agent, and the fiber. 8. The process according to claim 7, wherein treating at least a portion of the structure surface includes mechanical brushing of the structure surface. 9. A process for manufacturing a structure reinforced with a plurality of polymeric fibers protruding from at least a portion of its surface, the fibers being capable of endowing the at least a portion of the surface with biological or chemical resistance, the process comprising: obtaining a structure of a desired material and shape; coating at least a portion of the structure surface with a material comprising a plurality of polymeric fibers including at least one biological or chemical agent; and, treating the coating layer to expose the fibers' ends, such that the fibers protruding from the material along an outward facing surface; wherein the fiber concentration of the polymeric fibers protruding from at least a portion of the outward facing surface is 10 to 100 fibers per square millimeter. 10. The process according to claim 9, wherein the material comprising a plurality of polymeric fibers includes grout. 11. The process according to claim 10, wherein the coating includes applying the polymeric fibers by at least one of spraying or mechanical coating.
