Cement-based materials, reinforced with fibers and having greater toughness and ductility

摘要

'' CEMENT-BASED MATERIALS, REINFORCED WITH FIBERS AND HAVING GREATER TENACITY AND DUCTILITY '' A hybrid fiber reinforcing system is described, which increases concrete ductility in small and large crack openings, while avoiding the need of using steel fibers in high volumes (for example, 1%), taking into account the Young's modulus, developing high surface area to volume ratios, in order to obtain better anchoring, and using different relative lengths.
