Smart Engineering implements the quality control system in the Follo Line tunnel

Smart Engineering extends the contract signed with the Joint Venture AGJV, consortium of Acciona and Ghella. After successfully address the optimization of structural reinforcement of the Follo Line tunnel segments, Smart Engineering develops for AGJV a quality control system for fiber reinforced concrete, employing the Barcelona test and the inductive method. The Barcelona test is a methodology to characterize the post-cracking behavior and energy absorption of fiber reinforced concrete, developed at the Polytechnic University of Catalonia from the double punching test. This methodology, along with the inductive method for determining the content and fiber orientation in  fiber reinforced concrete allows a substantial improvement in quality control of this material. Such a methodology can reduce the dispersions associated with the mechanical characterization of the material, increases the number of tests and statistical representation, besides being cheaper than those applied as standard assay.

Smart Engineering is currently conducting an experimental campaign contrastation, in collaboration with the Universitat Politècnica de Catalunya. Thus, correlations between Barcelona test and standard beam test , used widely for the characterization of fiber reinforced concrete is proposed. The quality control system is expected to be implemented by the end of October using the test BCN and the inductive method together.
