Video Summary

Liberato Ferrara from Politecnico di Milano discusses the significant progress made by a committee focused on fiber-reinforced concrete. Over the past few years, they have published several documents addressing the entire value chain of this material—from conception, testing, identification of design parameters, to building structural applications. The session will detail methods for testing fresh concrete properties, mechanical properties, and durability aspects, including fiber dispersion, which is crucial for structural reliability. Ferrara highlights key documents, 2R and 9R, which cover fresh state and hardened state properties respectively. The 2R document explores fiber dispersion in self-compacting concrete and tests to monitor this, while the 9R document focuses on testing methodologies such as tension, bending, and various stress tests under different conditions. Ferrara underscores the global compatibility of standards and the committee's ongoing efforts to enhance the use of fiber-reinforced concrete in structural engineering.
