Numerical Simulations of SFRC Precast Tunnel Segments
No full textThe paper concerns precast tunnel segments for the new Line 9 of the Barcelona (Spain) Metro where the conventional reinforcement (rebars) may be partially substituted by steel fibers.
After the experimental determination of the material properties, NonLinear Fracture Mechanics analyses allowed to study the structural behavior of the tunnel segments with different types of reinforcement. Finally, an optimized reinforcement, based on a combination of rebars and steel fibers, is proposed
USE OF EAF STEEL SLAG AS AGGREGATE FOR CONCRETE PRODUCTION: ENVIRONMENTAL AND TECHNICAL ASSESSMENT
No full textThe progressive reduction of non-renewable natural resources has been a constant
concern relating to the protection of the environment that, at the same time,
encourages the use of alternative materials. So, preserving and minimizing the
consumption of natural resources have become an integral part of the day-to-day
activities operations across the entire glob
