FILIFORM ELEMENTS USABLE FOR REINFORCING MOULDABLE MATERIALS, PARTICULARLY CONCRETE

摘要

Filiform element usable for the reinforcement of mouldable materials, particularly concrete, said filiform element exhibiting ondulations regularly distributed throughout its length, and having the following characteristics: maximum amplitude of the ondulation from the longitudinal axis: 1 to 1,5 d; maximum wavelength: 10 d; minimum wavelength: 7 d; maximum fiber length: 65 d; minimum fiber length; 45 d; diameter (d) of the fiber: 1,2 mm at the most; nature of the steel: failure traction stress higher than 110 kg/mm<2> and smaller than 150 kg/mm<2>.
