Polypropylene Fibers for 3D Brace-Reinforced Concrete

This study proposes an innovative procedure for incorporating polymer fibers into concrete with the objective of enhancing its structural performance and durability. The integration of polymer fibers into advanced composite materials is driven by two primary objectives: first, to enhance the mechanical properties of the composite, and second, to reduce the carbon footprint associated with the conventional production of concrete. This novel approach, entails not only the development of enhanced mechanical properties but also the pursuit of sustainability, thereby facilitating a reduction in the carbon footprint associated with the production of conventional concrete. The study also explores the potential of fibers, beyond mechanical properties and in acoustic emission thus expanding the areas of benefit for sustainable construction. Through a detailed experimental investigation, this work assesses the performance of polymer fibers under various stress conditions, establishing new thresholds that could inform industry standards.
