FIBER REINFORCED CEMENTITIOUS MATERIALS WITH IMPROVED TOUGHNESS AND DUCTILITY

摘要

A hybrid fiber reinforcing system that enhances ductility of concrete at small and large crack openings, while avoiding the necessity of using steel fibers at high (e.g., 1 %) volumes, by taking into account Young's modulus, deploying large surface area to volume ratios for improved anchorage, and using different relative lengths.
