This study describes how the use of polymers, added to concrete in the form of binder, either as discrete elements (fibers), or continuous (strips), can limit the presence of cracks and, especially, avoid the corrosion processes in reinforced concrete structural elements. The effect of polyethylene terephthalate (PET) on concrete mix is especially considered, in detail. Different laboratory tests carried out on specimens of concrete reinforced with PET fibers derived from recycled water bottles are also described. Tests were conducted utilizing different shapes of PET fibers. In particular, the concrete-fibers adhesion and the global behavior of this fiber-reinforced concrete were observed in order to evaluate the possibility of more thorough investigation in the future. A solution to be better investigated in future studies is the use of plasma to improve the bond between the polymers and concrete (adherence).

Abstract
This study describes how the use of polymers, added to concrete in the form of binder, either as discrete elements (fibers), or continuous (strips), can limit the presence of cracks and, especially, avoid the corrosion processes in reinforced concrete structural elements. The effect of polyethylene terephthalate (PET) on concrete mix is especially considered, in detail. Different laboratory tests carried out on specimens of concrete reinforced with PET fibers derived from recycled water bottles are also described. Tests were conducted utilizing different shapes of PET fibers. In particular, the concrete-fibers adhesion and the global behavior of this fiber-reinforced concrete were observed in order to evaluate the possibility of more thorough investigation in the future. A solution to be better investigated in future studies is the use of plasma to improve the bond between the polymers and concrete (adherence).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
