Current methods to measure tensile strength and toughness in Steel Fiber Reinforced Concrete (SFRC) show a considerable scatter. That scatter makes difficult the quality control, in particular when such properties are taken into account in the evaluation of overall strength of the precast tunnel lining segments, as in the case of the Line 9 of the subway in Barcelona. In order to improve the material assessment procedure, the Double Punch Test (DPT) has been recovered for the quality control of… CONTINUE READING
