A structural reinforcing is foreseen for cement based materials comprising polymeric yarns ( 2 ) such as polypropylene and AR glass fibres ( 3 ) mixed together in weights that are similar in order to define a compound, and linking means ( 5 ) of the yarns ( 2 ) and fibres ( 3 ) to cement based materials ( 4 ), the yarns ( 2 ) and fibres ( 3 ) define the resistance properties of the materials ( 4 ) selectively up until a substantial failure of the same and in correspondence with the failure, and the compound being set in an amount between ten and forty percent of the weight of the cement used in the cement based materials ( 4 ).
